Abstract:

A cost effective, efficient thermal insulation composition that will have long shelf life and withstand severe high temperature and pressure conditions in high temperature solid propellant gas generators can be formed of an ethylene propylene, diene monomer EPDM-neoprene rubber binders containing silica powder filler and aramid fibers. The specific chemical constituents include EPDM elastomer, 2 Chlorobutadiene 1,3 elastomer, Silica hydrate, Polymerized Trimethyl Dihydroquinoline, Alkylated Diphenylamines and Diphenyl-p-Phenylendiamene, 40 a,a Bis Tert-Butylperoxy, Diisopropylbenzene, Napthenic Process Oil, Synthetic Polyterpene Resin, Aramid Fiber 0.25 inch, and Zinc Oxide, Technical.
