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 derivatives of benzothiazole.
Production Process Of Styrene - Rubber Antioxidant, Rubber
Styrene is an organic compound that can be formed from two substances, benzene and ethylene. Styrene is a colorless and transparent liquid, which easily pollutes drinking water, soil, and surface water, and has strong volatility.
Factory - Rubber Antioxidant, Rubber Activator, Rubber
Richest Group is a high-tech private company engaged in the rubber raw materials, supplying rubber antioxidant, rubber accelerator, solvent, fine chemical, etc. Richest Group has perfectly completed the strategic arrangement by setting up the production base and quality-control center in Shandong Province, the R&D center in Shanghai City.
Rubber compounding was performed on a two-roll mill (Lab Walzwerk MT 6″×13″, Rubicon, Germany) in a three-stage process. In the first stage, the rubber was mixed with zinc oxide, stearic acid, CB, and Struktol or IPPD. Then the rubber/MLG masterbatch was added to the rubber compound in the second stage.
Vulcanization. Vulcanization is a chemical process in which the rubber is heated with sulphur, accelerator and activator at 140–160°C. The process involves the formation of cross-links between long rubber molecules so as to achieve improved elasticity, resilience, tensile strength, viscosity, hardness and weather resistance.
Zinc Oxide in Rubber Industry - Formulations & Manufacturing
Take a role as an activator or accelerator. Acts as a sour agent in the rubber vulcanization, it absorbs some of the vulcanization of the production of acidic substances. It can improve the thermal properties of the compound. Zinc oxide acts as the key ingredient with 50-60% being used in rubber industry.
