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.

Glazed pottery or aluminium or plastic cups became more common in Kerala and other countries. The cups are supported by a wire that encircles the tree.

This wire incorporates a spring so it can stretch as the tree grows. The latex is led into the cup by a galvanised "spout" knocked into the bark.

Tapping normally takes place early in the morning, when the internal pressure of the tree is highest. A good tapper can tap a tree every 20 seconds on a standard half-spiral system, and a common daily "task" size is between and trees.

Trees are usually tapped on alternate or third days, although many variations in timing, length and number of cuts are used.

These slanting cuts allowed latex to flow from ducts located on the exterior or the inner layer of bark cambium of the tree. Since the cambium controls the growth of the tree, growth stops if it is cut.

Thus, rubber tapping demanded accuracy, so that the incisions would not be too many given the size of the tree, or too deep, which could stunt its growth or kill it.

It is usual to tap a pannel at least twice, sometimes three times, during the tree's life. The economic life of the tree depends on how well the tapping is carried out, as the critical factor is bark consumption.

The latex-containing tubes in the bark ascend in a spiral to the right. For this reason, tapping cuts usually ascend to the left to cut more tubes.

The trees drip latex for about four hours, stopping as latex coagulates naturally on the tapping cut, thus blocking the latex tubes in the bark.

Tappers usually rest and have a meal after finishing their tapping work, then start collecting the liquid "field latex" at about midday.

The four types of field coagula are "cuplump", "treelace", "smallholders' lump" and "earth scrap". Each has significantly different properties. The latex that coagulates on the cut is also collected as "tree lace".

Latex that drips onto the ground, "earth scrap", is also collected periodically for processing of low-grade product.

Cup lump is the coagulated material found in the collection cup when the tapper next visits the tree to tap it again.

It arises from latex clinging to the walls of the cup after the latex was last poured into the bucket, and from late-dripping latex exuded before the latex-carrying vessels of the tree become blocked.

It is of higher purity and of greater value than the other three types. Tree lace is the coagulum strip that the tapper peels off the previous cut before making a new cut.

It usually has higher copper and manganese contents than cup lump. Both copper and manganese are pro-oxidants and can damage the physical properties of the dry rubber.

Smallholders' lump is produced by smallholders who collect rubber from trees far from the nearest factory. Many Indonesian smallholders, who farm paddies in remote areas, tap dispersed trees on their way to work in the paddy fields and collect the latex or the coagulated latex on their way home.

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.

Its major commercial success came only after the vulcanization process was invented by Charles Goodyear in Natural rubber continues to hold an important place in the market today; its resistance to heat buildup makes it valuable for tires used on racing cars, trucks, buses, and airplanes.

Nevertheless, it constitutes less than half of the rubber produced commercially; the rest is rubber produced synthetically by means of chemical processes that were partly known in the 19th century but were not applied commercially until the second half of the 20th century, after World War II.

Among the most important synthetic rubbers are butadiene rubber , styrene-butadiene rubber , neoprene , the polysulfide rubbers thiokols , butyl rubber , and the silicones.

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.

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. Southeast Asia is particularly well situated for rubber culture; so too are parts of South Asia and West Africa.
