This specification covers a silicone elastomer in the form of molded sheet and shapes, color coded white in accordance with ARP1527.This elastomer has been used typically for parts in pressurized aircraft compartment interiors such as grommets, tube supports, clamp cushions, bushings and seals where flame resistance, low smoke density and non-toxic gas generation are required, but usage is not limited to such applications. Each application should be considered separately.
