RUBBER CHEMISTRY Läroverket i Småland AB
chemical vulcanizing agents are used to create the chemical transverse bonds between rubber macromolecules (such as sulphur, peroxides, metal oxides, resins, quinones and others), which can react with appropriate functional rubber groups in the process of vulcanization to create transverse bonds between them. The cross-
Isobutene-isoprene rubber (Butyl, IIR), and Nitrile-butadiene rubber (NBR), which are crosslinked by using sulfur as a vulcanizing agent. The basic ingredients for a sulfur cure are: Sulfur or sulfur donor (crosslinker), Zinc oxide and fatty

Recycled Rubber. Genesis Evolution Compounds© (GEC©) nanopolymerization system allows previously vulcanized rubber crumbs to become chemically reactivated to create a new compounding material. GEC© can be used for SBR, PBR, IR, Butyl and EPDM rubber; it can be used with any vulcanized rubber crumbs.
Sulfur Vulcanization
Vulcanization is a chemical process that converts natural rubber and other polydiene elastomers into cross-linked polymers. The most common vulcanization agent is sulfur. It forms bridges between individual polymer molecules when heated with rubber. Often a catalyst and initiator is added to accelerate the vulcanization process.
Resin vulcanizing agent. Mainly used for butyl rubber vulcanization, so that it has excellent heat resistance and high temperature performance. At present the industry has been widely used, to speed up the curing rate, the general need to add stannous chloride as the active agent. Resin curing agent in the processing of rubber plastic can
