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 PROCESSING TECHNOLOGY
Rubber Processing and Shaping •Production of rubber goods consists of two basic steps: 1. Production of the rubber itself Natural rubber is an agricultural crop Synthetic rubbers are made from petroleum 2. Processing into finished goods, consisting of: (a) Compounding (b) Mixing (c) Shaping (d) Vulcanizing
Rubber - Protective chemicals
Rubber - Rubber - Protective chemicals: Certain additives confer resistance to heat, sunlight, oxygen, and ozone. Amines, particularly paraphenylene diamines, are powerful retarders of oxidation, or antioxidants. Added to rubber compounds in small amounts (1–2 percent), they appear to disrupt the free-radical oxidation reactions that lead either to molecular rupture and softening or to
Rubber-Processing - Specialty Chemicals Update Program (SCUP
Global consumption of rubber/processing chemicals will grow at an average annual rate of 3.5% during 2018-23, driven primarily by the markets in Asia, particularly China and Other Asia. Rubber/processing chemicals, in general, are considered as a group to be specialty chemicals.
Blooming is undesirable in rubber processing. When sulfur bloom appears before vulcanization, the rubber is deprived of the crosslinking agent. Sulfur bloom after vulcanization indicates incomplete vulcanization. In rubber processing, ingredients other than sulfur can "bloom", including antioxidants, fatty acids, and accelerators.

Outgassing of Silicone Elastomers
ISC 2002 Page 2 of 9 Post-Curing Post-curing is one of the principal tools to mitigate outgassing. Post-cure is a process that removes the volatiles from the cross-linked silicone rubber by diffusion and evaporation and is carried out at a temperature greater than the service temperature for the part. (The
