    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

  • natural rubber

    Natural rubber

    Natural rubber offers good elasticity, while synthetic materials tend to offer better resistance to environmental factors such as oils, temperature, chemicals and ultraviolet light. "Cured rubber" is rubber that has been compounded and subjected to the vulcanisation process to create cross-links within the rubber matrix.

  • rubber - additives

    Rubber - Additives

    Rubber - Rubber - Additives: A number of ingredients are added to both natural and synthetic rubber in order to obtain certain desirable properties. By convention, mix formulations begin with the amount of the designated elastomer—for instance, natural rubber (NR), butadiene rubber (BR), or styrene-butadiene rubber (SBR)—given as 100 parts by weight.

    Rubber-Processing - Specialty Chemicals Update Program (SCUP

    The markets for most of the rubber/processing chemicals track the general production and consumption of the major synthetic rubbers (e.g., SBR, PBR, EPDM), as well as the natural rubber markets. The tire and automotive industries have a huge impact on demand for rubber/processing chemicals.

    Rubber is a material that can be achieved whether by processing latex naturally secreted by certain plants (eg, rubber tree), or by an industrial process. Rubbers are also used in many industrial applications and daily (gloves, condoms, caps, rubber bands, automotive, construction and buildings, household appliances, etc.).

    Natural Rubber and Synthetic Rubber Preparation and Properties

    This latex rubber is mainly found in the countries like Brazil, India, Indonesia, Malaysia and Sri Lanka. It is made by the polymerization of isoprene (2 methyl-1, 3-butadiene) which has a chemical formula (C 5 H 8) n and it is known as cis- 1, 4- polyisoprene. In simple words, we can say that they are made by loosely joining the monomers of
