摘要：
The molecular design of semi-inorganic polymers has produced polysilphenylene-siloxane and polyphosphazene elastomers having comparable fire safety to heat resistant engineering plastics. In flaming combustion a polyphosphazene rubber had a four times lower peak heat release rate than the polyurethane elastomer currently used in fire-blocked aircraft seat Cushions. The addition of expandable graphite flakes to polyurethane and polyphosphazene elastomers reduces their peak heat release rates by factors of seven and five, respectively.
