Frequently Asked Questions (FAQ's)

Who Discovered Rubber?

The Indians of central & south America were the first to utilize rubber’s unique properties. Christopher Columbus watched them play a game called “Tlachtlic” a vigorous cross between basketball and football, with the object of directing a rubber ball though a stone ring.

Who used it first & named “Rubber”?

In England,Joseph Prestley best know of his discovery of oxygen noted the pencil marks could be “rubbed out” by the substance from this early use, Rubber Derived its name.

What discovery marked the beginning of modern rubber technology?

Prior to 1839, the properties of rubber were dictated by the surrounding temperature, during the hot summer, rubber was sticky and malleable. While it became hard and brittle in the colder months that was finally remedied by the discovery of the process of vulcanization a mixture of rubber was dropped accidentally upon a hot stove. When it was removed, the material was on longer affected by temperature Despite of stretching, It always retumed to its original shape. This process of vulcanization made it possible to use rubber in tain coal. Overshoes and eventually, many other products including types.

Types of Rubber?

Tow types Rubber in common use today. These are Natural & Synthetic Rubber, Natural Rubber comes foram a tree Hevea brasiliensis.when tree natures at the ago of six or seven years, the latex (milk like material) is collected from a diagonal incision in the tree trunk. The tapping process dose not affect the health of the tree and tree wound later heals itself Synthetic rubber is mead by man from petrochemical feed Stocks, Crude oil is the principal raw material.

Where is Natural Rubber Produced?

Today more than 90% of natural rubber supply comes from south-East Asian country. A rubber tree require a hot,dampclimate, they grow only in the “ Rubber Belt “ an equatorial zone that stertches around the world. In 1876, the English recognition of the difficulties of securing quality rubber from the jungle hit upon the idea of growing rubber on plantations from their efforts,the cultivated rubber terr plantations of southest Asian and Africa have developed.

What accelerated the development of synthetic Rubber?

The united states & Germany were Cut of from virtually all of its sources of natural rubber in the pacific during world war ll . In order to meet the needs for this vital material, the Government built synthetic Rubber plants and the industry operated them.

How is synthetic Rubber produced?

General purpose synthetic rubber has its origin in two gases:BUTADUENE, a bye- product of petroleum refining, and styrene capture either in a cooking process or as a petroleum refining bye-product, when two are mixed in the persence of soapsuds in reator, liquid latex results. The dry rubber in this milky liquid is then coagulated into crumbs, washed dried and baled ready for shipment.

What are different types of synthetic Rubber?

Styene Butadiene rubber, poly- butadiene Rubber, butly Rubber, Nitrile Rubber, Chloroprene Rubber, Hypalon, EPDM, VAMAC silcones, flouroelastomers, Poly-urethanes.

What is the use of Rubber?

60% of the production is being used in Tyre manufacturing while 40% in used in nontyre applicatins i.e, Hoses belting automobile parts surgical goods, Glovers, industrial parts.
