RUBBER-MOLDING COMPOSITION FOR ELECTRICITY

摘要

PURPOSE: To provide a novel rubber forming composition for electrical use, particularly provide a composition for matching PST and a PST made from this composition by improving the tearing-off strength of silicon modified EPDM having cold resistance, weather resistance and heat resistance. CONSTITUTION: 100 wt part of silicon modified ethylene-propylene diene terpolymer and particle-like polytetrafluoroethylene and a quantity of 0.5 to 2 wt part of moribdenum disulfide effective for uniformly mixing this particle- like polytetrafluoroethylene in terpolymer are included.
