EPDM Application SPchem V.E/C VS CTP(PVI) . According to their chemical structure, retarders mainly are nitroso compoun d, organic acid, su lfenamide. Among them, nitroso compound and organic acid bring negative effects, such as dispersion problem, blooming, curing delay, and staining, while sulfenamide can avoide these limits, such as CTP and retarder E.
The global rubber antioxidant market can be segmented based on application, type, and region. In terms of application, the rubber antioxidant market can be segmented into tire, convenor belts, tubes, transmission belts, hoses, and others. Tire is a major application segment of the rubber antioxidant market.
Rubber Vulcanizing Agent | Sunsine Insoluble Sulfur Wholesaler
Insoluble sulphur is primarily used in the rubber industry. Its advantage over ground natural sulphur is that it does not cause bloom, and that it does not dissolve and migrate in rubber. The S8 ring molecules present in soluble sulphur at room temperature open at temperatures above 158 °C, allowing chains of sulphur to combine with one another to form polymeric sulphur.

Other vulcanizing agents include amine compounds for the cross-linking of fluorocarbon rubbers, metal oxides for chlorine-containing rubbers (notably zinc oxide for chloroprene rubber) and phenol-formaldehyde resins for the production of heat-resistant butyl rubber vulcanizates. Accelerator, in the rubber industry, is added with a curing agent
The compound is a prototypical zinc dithiocarbamate, a broad class of coordination complexes with the formulae Zn(R 2 NCS 2) 2, where R can be widely varied. Such compounds are produced by first treating a secondary amine with carbon disulfide to give the dithiocarbamate (R 2 NCS 2 − ), which is then treated with zinc salts, as illustrated ...
