rubber vulcanization accelerators in sri lanka
Property improvements of natural rubber and low density
Sulfur vulcanization of EPDM rubber and other elastomers is normally performed in the presence of activator and accelerators. It is proven, that the mechanism of sulfur vulcanization of EPDM is more or less similar to the mechanism, which is normally accepted for polydiene elastomers (Chapman and Porter, 1998).
