In major areas, latex is allowed to coagulate in the collection cup. The coagulated lumps are collected and processed into dry forms for sale.

Natural rubber is used extensively in many applications and products, either alone or in combination with other materials.

In most of its useful forms, it has a large stretch ratio and high resilience, and is extremely waterproof. The major commercial source of natural rubber latex is the Amazonian rubber tree Hevea brasiliensis , a member of the spurge family , Euphorbiaceae.

This species is preferred because it grows well under cultivation. A properly managed tree responds to wounding by producing more latex for several years.

Congo rubber , formerly a major source of rubber, came from vines in the genus Landolphia L. Dandelion milk contains latex.

The latex exhibits the same quality as the natural rubber from rubber trees. In the wild types of dandelion, latex content is low and varies greatly.

In Nazi Germany , research projects tried to use dandelions as a base for rubber production, but failed. Some produce other desirable materials, for example gutta-percha Palaquium gutta [5] and chicle from Manilkara species.

Others that have been commercially exploited, or at least showed promise as rubber sources, include the rubber fig Ficus elastica , Panama rubber tree Castilla elastica , various spurges Euphorbia spp.

The term gum rubber is sometimes applied to the tree-obtained version of natural rubber in order to distinguish it from the synthetic version.

The first use of rubber was by the indigenous cultures of Mesoamerica. The earliest archeological evidence of the use of natural latex from the Hevea tree comes from the Olmec culture, in which rubber was first used for making balls for the Mesoamerican ballgame.

Rubber was later used by the Maya and Aztec cultures — in addition to making balls Aztecs used rubber for other purposes such as making containers and to make textiles waterproof by impregnating them with the latex sap.

This has been referred to as the first scientific paper on rubber. It slowly made its way around England. Giovanni Fabbroni is credited with the discovery of naphtha as a rubber solvent in South America remained the main source of latex rubber used during much of the 19th century.

The rubber trade was heavily controlled by business interests but no laws expressly prohibited the export of seeds or plants. Only 2, of these germinated.

Malaya now Peninsular Malaysia was later to become the biggest producer of rubber. In the early s, the Congo Free State in Africa was also a significant source of natural rubber latex, mostly gathered by forced labor.

King Leopold II's colonial state brutally enforced production quotas. Tactics to enforce the rubber quotas included removing the hands of victims to prove they had been killed.

Soldiers often came back from raids with baskets full of chopped-off hands. Villages that resisted were razed to encourage better compliance locally.

See Atrocities in the Congo Free State for more information on the rubber trade in the Congo Free State in the late s and early s. In India , commercial cultivation was introduced by British planters, although the experimental efforts to grow rubber on a commercial scale were initiated as early as at the Calcutta Botanical Gardens.

The first commercial Hevea plantations were established at Thattekadu in Kerala in India today is the world's 3rd largest producer and 4th largest consumer.

He distributed rubber seeds to many planters and developed the first technique for tapping trees for latex without causing serious harm to the tree.

Before World War II significant uses included door and window profiles, hoses, belts, gaskets, matting , flooring and dampeners antivibration mounts for the automotive industry.

The use of rubber in car tires initially solid rather than pneumatic in particular consumed a significant amount of rubber. Gloves medical, household and industrial and toy balloons were large consumers of rubber, although the type of rubber used is concentrated latex.

Significant tonnage of rubber was used as adhesives in many manufacturing industries and products, although the two most noticeable were the paper and the carpet industries.

Rubber was commonly used to make rubber bands and pencil erasers. Rubber produced as a fiber, sometimes called 'elastic', had significant value to the textile industry because of its excellent elongation and recovery properties.

For these purposes, manufactured rubber fiber was made as either an extruded round fiber or rectangular fibers cut into strips from extruded film.

Because of its low dye acceptance, feel and appearance, the rubber fiber was either covered by yarn of another fiber or directly woven with other yarns into the fabric.

Rubber yarns were used in foundation garments. While rubber is still used in textile manufacturing, its low tenacity limits its use in lightweight garments because latex lacks resistance to oxidizing agents and is damaged by aging, sunlight, oil and perspiration.

The textile industry turned to neoprene polymer of chloroprene , a type of synthetic rubber, as well as another more commonly used elastomer fiber, spandex also known as elastane , because of their superiority to rubber in both strength and durability.

Rubber exhibits unique physical and chemical properties. Rubber's stress—strain behavior exhibits the Mullins effect and the Payne effect and is often modeled as hyperelastic.

Rubber strain crystallizes. Due to the presence of weakened allylic C-H bonds in each repeat unit , natural rubber is susceptible to vulcanisation as well as being sensitive to ozone cracking.

The two main solvents for rubber are turpentine and naphtha petroleum. Because rubber does not dissolve easily, the material is finely divided by shredding prior to its immersion.

An ammonia solution can be used to prevent the coagulation of raw latex. On a microscopic scale, relaxed rubber is a disorganized cluster of erratically changing wrinkled chains.

In stretched rubber, the chains are almost linear. The restoring force is due to the preponderance of wrinkled conformations over more linear ones.

For the quantitative treatment see ideal chain , for more examples see entropic force. Cooling below the glass transition temperature permits local conformational changes but a reordering is practically impossible because of the larger energy barrier for the concerted movement of longer chains.

The parallel chains of stretched rubber are susceptible to crystallization. This takes some time because turns of twisted chains have to move out of the way of the growing crystallites.

Crystallization has occurred, for example, when, after days, an inflated toy balloon is found withered at a relatively large remaining volume.

Where it is touched, it shrinks because the temperature of the hand is enough to melt the crystals. Vulcanization of rubber creates di- and polysulfide bonds between chains, which limits the degrees of freedom and results in chains that tighten more quickly for a given strain, thereby increasing the elastic force constant and making the rubber harder and less extensible.

Raw rubber storage depots and rubber processing can produce malodour that is serious enough to become a source of complaints and protest to those living in the vicinity.

Microbial impurities originate during the processing of block rubber. These impurities break down during storage or thermal degradation and produce volatile organic compounds.

When latex concentrate is produced from rubber, sulphuric acid is used for coagulation. This produces malodourous hydrogen sulphide.

The industry can mitigate these bad odours with scrubber systems. Latex is the polymer cis-1,4-polyisoprene — with a molecular weight of , to 1,, daltons.

Polyisoprene can also be created synthetically, producing what is sometimes referred to as "synthetic natural rubber", but the synthetic and natural routes are different.

Natural rubber is an elastomer and a thermoplastic. Once the rubber is vulcanized, it is a thermoset.

Most rubber in everyday use is vulcanized to a point where it shares properties of both; i. The final properties of a rubber item depend not just on the polymer, but also on modifiers and fillers, such as carbon black , factice , whiting and others.

Rubber particles are formed in the cytoplasm of specialized latex-producing cells called laticifers within rubber plants. The membrane allows biosynthetic proteins to be sequestered at the surface of the growing rubber particle, which allows new monomeric units to be added from outside the biomembrane, but within the lacticifer.

The rubber particle is an enzymatically active entity that contains three layers of material, the rubber particle, a biomembrane and free monomeric units.

The biomembrane is held tightly to the rubber core due to the high negative charge along the double bonds of the rubber polymer backbone.

The monomer adds to the pyrophosphate end of the growing polymer. The reaction produces a cis polymer. The initiation step is catalyzed by prenyltransferase , which converts three monomers of isopentenyl pyrophosphate into farnesyl pyrophosphate.

The required isopentenyl pyrophosphate is obtained from the mevalonate pathway, which derives from acetyl-CoA in the cytosol. Though rubber is known to be produced by only one enzyme, extracts of latex host numerous small molecular weight proteins with unknown function.

The proteins possibly serve as cofactors, as the synthetic rate decreases with complete removal. Since the bulk is synthetic, which is derived from petroleum, the price of natural rubber is determined, to a large extent, by the prevailing global price of crude oil.

The three largest producers, Thailand , Indonesia 2. Natural rubber is not cultivated widely in its native continent of South America due to the existence of South American leaf blight , and other natural predators.

Rubber latex is extracted from rubber trees. The soil requirement is well-drained, weathered soil consisting of laterite , lateritic types, sedimentary types, nonlateritic red or alluvial soils.

Many high-yielding clones have been developed for commercial planting. In places such as Kerala and Sri Lanka where coconuts are in abundance, the half shell of coconut was used as the latex collection container.

As it is often impossible to preserve the latex sufficiently to get it to a factory that processes latex in time for it to be used to make high quality products, and as the latex would anyway have coagulated by the time it reached the factory, the smallholder will coagulate it by any means available, in any container available.

Some smallholders use small containers, buckets etc. Little care is taken to exclude twigs, leaves, and even bark from the lumps that are formed, which may also include tree lace.

Earth scrap is material that gathers around the base of the tree. It arises from latex overflowing from the cut and running down the bark, from rain flooding a collection cup containing latex, and from spillage from tappers' buckets during collection.

It contains soil and other contaminants, and has variable rubber content, depending on the amount of contaminants. Earth scrap is collected by field workers two or three times a year and may be cleaned in a scrap-washer to recover the rubber, or sold to a contractor who cleans it and recovers the rubber.

It is of low quality. Latex coagulates in the cups if kept for long and must be collected before this happens. The collected latex, "field latex", is transferred into coagulation tanks for the preparation of dry rubber or transferred into air-tight containers with sieving for ammoniation.

Ammoniation preserves the latex in a colloidal state for longer periods of time. Latex is generally processed into either latex concentrate for manufacture of dipped goods or coagulated under controlled, clean conditions using formic acid.

Processing for these grades is a size reduction and cleaning process to remove contamination and prepare the material for the final stage of drying.

Natural rubber is often vulcanized - a process by which the rubber is heated and sulfur , peroxide or bisphenol are added to improve resistance and elasticity and to prevent it from perishing.

Natural rubber latex is shipped from factories in Southeast Asia , South America , and West and Central Africa to destinations around the world.

As the cost of natural rubber has risen significantly and rubber products are dense, the shipping methods offering the lowest cost per unit weight are preferred.

Depending on destination, warehouse availability, and transportation conditions, some methods are preferred by certain buyers. In international trade, latex rubber is mostly shipped in foot ocean containers.

Inside the container, smaller containers are used to store the latex. Uncured rubber is used for cements; [33] for adhesive, insulating, and friction tapes; and for crepe rubber used in insulating blankets and footwear.

Vulcanized rubber has many more applications. Resistance to abrasion makes softer kinds of rubber valuable for the treads of vehicle tires and conveyor belts, and makes hard rubber valuable for pump housings and piping used in the handling of abrasive sludge.

The flexibility of rubber is appealing in hoses, tires and rollers for devices ranging from domestic clothes wringers to printing presses; its elasticity makes it suitable for various kinds of shock absorbers and for specialized machinery mountings designed to reduce vibration.

Its relative gas impermeability makes it useful in the manufacture of articles such as air hoses, balloons, balls and cushions.

The resistance of rubber to water and to the action of most fluid chemicals has led to its use in rainwear, diving gear, and chemical and medicinal tubing, and as a lining for storage tanks, processing equipment and railroad tank cars.

Because of their electrical resistance, soft rubber goods are used as insulation and for protective gloves, shoes and blankets; hard rubber is used for articles such as telephone housings, parts for radio sets, meters and other electrical instruments.

The coefficient of friction of rubber, which is high on dry surfaces and low on wet surfaces, leads to its use for power-transmission belting and for water-lubricated bearings in deep-well pumps.

Indian rubber balls or lacrosse balls are made of rubber. Around 25 million tonnes of rubber are produced each year, of which 30 percent is natural.

The top end of latex production results in latex products such as surgeons' gloves, condoms, balloons and other relatively high-value products.

The mid-range which comes from the technically specified natural rubber materials ends up largely in tires but also in conveyor belts, marine products, windshield wipers and miscellaneous goods.

Natural rubber offers good elasticity, while synthetic materials tend to offer better resistance to environmental factors such as oils, temperature, chemicals and ultraviolet light.

Some people have a serious latex allergy , and exposure to natural latex rubber products such as latex gloves can cause anaphylactic shock.

The antigenic proteins found in Hevea latex may be deliberately reduced though not eliminated [35] through processing.

Latex from non- Hevea sources, such as Guayule , can be used without allergic reaction by persons with an allergy to Hevea latex. Some allergic reactions are not to the latex itself, but from residues of chemicals used to accelerate the cross-linking process.

Although this may be confused with an allergy to latex, it is distinct from it, typically taking the form of Type IV hypersensitivity in the presence of traces of specific processing chemicals.

Synthetic rubbers, like natural rubbers, can be toughened by vulcanization and improved and modified for special purposes by reinforcement with other materials.

Essential properties of the polymers used to produce the principal commercial rubbers are listed in the table. Commercially, natural rubber is obtained almost exclusively from Hevea brasiliensis , a tree indigenous to South America, where it grows wild to a height of 34 metres feet.

Cultivated in plantations, however, the tree grows only to about 24 metres 80 feet because carbon, necessary for growth, is also an essential constituent of rubber.

Since only atmospheric carbon dioxide can supply carbon to the plant, the element has to be rationed between the two needs when the tree is in active production.

Also, with foliage limited to the top of the tree to facilitate tapping , the intake of carbon dioxide is less than in a wild tree. Other trees, shrubs, and herbaceous plants produce rubber, but, because none of them compares for efficiency with Hevea brasiliensis, industry botanists have concentrated their efforts exclusively on this species.

In the cultivation of Hevea, the natural contours of the land are followed, and the trees are protected from wind. Cover crops planted adjacent to the rubber trees hold rainwater on sloping ground and help to fertilize the soil by fixing atmospheric nitrogen.

Standard horticultural techniques, such as nursery growing of hardy rootstocks and grafting on top of them, hand pollination, and vegetative propagation cloning to produce a genetically uniform product, are also employed.

Hevea grows only within a well-defined area of the tropics and subtropics where frost is never encountered.

Heavy annual rainfall of about 2, mm inches is essential, with emphasis on a wet spring. As a consequence of these requirements, growing areas are limited.
