Production of rubber product for food application

Abstract

Abstract PURPOSE: Specific vulcanizing accelerator and, when necessary, specific fillers and reinforcing agents are added to an ethylene-propylene rubber to produce title vulcanized rubber products satisfying the safety standards of resin roducts for food application. CONSTITUTION: To 100 parts b wt of an ethylene-propylene rubber with an ethylene content of 20W95 mole% are added 10 or less parts of at least one selected from zincdibutyl, zincmethyl, zincethyl dithiocarbamates, dipentamethylene thiuramhexasulfide and tetramethylthiuram monosulfide as a vulcanizing accelerator, and, when necessary, less than 150 parts of one selected from furnace black, superfine particles of magnesium silicate, clay with untreated surfaces mainly consisting of aluminum silicate containing 35W65% of silica and 25W45% of alumina and aluminum hydroxide as a filler or reinforcing agent.
