Methods of promoting the radiation-induced cross linking of poly(tetrafluoro-ethylene-co-perfluoromethyl vinyl ether) (TFE/PMVE) have been investigated. Greater control of the crosslinking and chain-scission reactions was achieved by varying the radi

Incorporation of 1 wt % of triallyl isocyanurate (TAIC) significantly enhanced the radiation crosslinking of the perfluoroelastomer, poly(tetrafluoroethylene-co-perfluoromethylvinyl ether) (TFE/PMVE). The dose for gelation was lowered by 70% with the

Pre-shaped perfluoro-elastomeric articles were crosslinked by electron-beam irradiation. Doses of 10-15 Mrad are adequate to give a gel content of more than 95%. Irradiation experiments were carried out on the pure polymer free of fillers, processing

Fluorocarbon elastomers represent a broad class of high performance elastomers which combine excellent thermal, oxidative and fluid resistance with very good tensile and compression-set resistance properties. These polymers are characterized by havin
