Abstract

PURPOSE: The titled composition, which has improved sealing property and a small permanent compression set at a high temperature, is nontoxic to food and hygiene, and prepared by adding a formaldehyde resin and zinc flower as crosslinking agents in specific amounts instead of a sulfur vulcanizing agent to chlorinated butyl rubber.
CONSTITUTION: ThreeWeight pts.wt. a formaldehyde resin, e.g. an alkylphenol- formaldehyde resin, and 4W6pts.wt. zinc flower as crosslinking agents instead of sulfur as a vulcanizing agent and a vulcanization accelerator are added to 100pts.wt. chlorinated butyl rubber to give the aimed composition.
EFFECT: Procuring the acceptance of the standard of food sanitation test and a small permanent compression set at 100W120°C.
USE: A material for a gasket incorporated in joints of the piping in a solar heated hot water supplying system (solar system).
