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
Accelerators for Rubber — ChemSpec Ltd.
A historical leader in the rubber market, the group continues its development in Coatings and Fine Chemicals, by strengthening or gaining new positions. In 2018, SAFIC-ALCAN underwent a re-branding campaign. This re-branding affects both the industrial performance and cosmetics products.
Rubber Chemicals — Performance Additives
Polymer Processing Additives for all your adventures. Scroll Performance Additives Produce a broad range of Rubber processing additives for natural and synthetic rubber and various special elastomers as well as a range of special accelerators for solid and liquid rubber.
thick, rubber-covered roll may have a curing period of several hours at temperatures of 200-300°F; on the other hand, an insulated electric wire may have its rubber covering cured in a matter of seconds at 388°F. The latter temperature is that of saturated steam at 200 psi pressure used in the continuous vulcanization of rubber-insulated wiring.
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
Accelerator | rubber manufacturing
Accelerator, in the rubber industry, any of numerous chemical substances that cause vulcanization (q.v.) of rubber to occur more rapidly or at lower temperatures. Many classes of compounds act as accelerators, the most important being organic materials containing sulfur and nitrogen, especially

Changes Of Rubber Additives Market In China And American In . In 1988, the United States consumed 2.88 million tons of rubber, and produced 160000 tons of rubber additives (including 38000 tons of accelerators and 100000 tons of anti-aging agents). 1.2 There are many factories for rubber auxiliaries.
