VISCOELASTIC EVALUATION OF SILICONE RUBBER AND ETHYLENE PROPYLENE

摘要

Initial evaluation studies were made on two materials to determine their suitability as alternates to a silicone rubber for reactor applica¬tions. Of the two materials studied, ethylene propylene and chlorosulfonated polyethylene, the ethylene propylene has the lowest compression set and stress relaxation;and consequently, appears to be the best candidate. It has a higher stress relaxation rate than the silicone but its radiation resistance is superior.
