摘要:
An encapsulating compound for deep submergence use is a butyl and chlorobutyl copolymer containing reactive chlorine and having added thereto specific fillers, activators, accelerators and curing agents. The resulting compound is useful in encapsulating components exposed to deep sea environments. One such specific compound includes the following constituents: Parts per 100 BY WEIGHT OF AN ELASTOMERIC ISOBUTYLENE-ISOPRENE COPOLYMER CONTAINING REACTIVE CHLORINE 50 FILLER 10 LEAD MONOXIDE 1 FLAKED STEARIC ACID 3 POLYETHELYENE PLASTICIZER 2/1.5 DIPHENYLGUANIDINE AND 2-MERCAPTOIMIDAZOLINE ACCELERATORS 1 MAGNESIUM OXIDE ACTIVATOR AND 5 ZINC OXIDE CURING AGENT.
