Phenolic Curing Resin
Phenolic curing resins are heat-reactive phenol-formaldehyde resins used to crosslink unsaturated rubbers (especially butyl, EPDM, and other low-unsaturation elastomers). Crosslinking occurs at the double bonds on the rubber molecule, not through sulfur. They give heat-stable vulcanizates with good compression set and chemical resistance.
Industry Applications
Rubber vulcanization for bladders, hoses, belts, seals, and other heat-resistant molded goods.
