TAIC is widely used as a coagent for peroxide crosslinking or radiation crosslinking of Chlorinated Polyethylene (CPE), EPDM, Fluroelaster and so on.
TAIC is availavle for linking by x-ray, y-ray electron or ultra violet ray radiation and the product polyolefines have the superior insolubility to solvents and the tensile strength at high temperature could be improved.
TAIC is effective modifier to heat resistance with increasing of crosslinking density for peroxide crosslinking denisty for peroxide crosslinking of CPE. Since TAIC acts as an acceptor of HCI which is envolved from CPE at crosslinking reaction and deteriorates its physical properties.
TAIC is the most effective coagent for crosslinking EVA.
TAIC preferably contributes to promote crosslinking rate and also to improve its heat resistance, compression set and abrasion resistance
