    Natural rubber

    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. Carbon black is often used as an additive to rubber to improve its strength, especially in vehicle tires, which account for about 70% (~9 million tons) of

    Rubber - Processing

    Rubber - Rubber - Processing: Rubber processing consists of four basic steps: (1) mastication, when the elastomer is sheared and the molecules are broken down to give easier flow, (2) mixing, usually carried out immediately after mastication, when additives are incorporated, (3) shaping of the viscous mass, for example, by extrusion or molding, and (4) curing, when the polymer molecules become

    Rubber - Tapping and coagulation

    Rubber - Rubber - Tapping and coagulation: When the bark of the Hevea tree is partially cut through (tapped), a milky liquid exudes from the wound and dries to yield a rubbery film. The biological function of this latex is still obscure: it may help wound-healing by protecting the inner bark, or it may serve other biochemical functions. The latex consists of an aqueous suspension of small

    Rubber-Processing - Specialty Chemicals Update Program (SCUP

    Rubber/processing chemicals, in general, are considered as a group to be specialty chemicals. These chemicals can aid in improving the resistance of rubber to heat, oxidation, sunlight, ozone, and mechanical stresses. Furthermore, rubber/processing chemicals also greatly improve the overall process of vulcanization.

    It is a process to obtain cross-linking of elastomer molecules to make rubber stiffer and stronger as well as retains extensibility at the same time. All types of SBR are vulcanized using the same vulcanization agents as for natural rubber. Styrene-butadiene rubber can be vulcanized using sulfur, sulfur donor systems and peroxides. Sulfur is
