Performance and use
This product is insoluble in water, soluble in toluene, etc. It has excellent compression
deformation and excellent resistance to saturated vapor pressure. In the aviation,
electronics, machinery, chemical and other industrial sectors, it can be used to
manufacture high and low temperature resistant sealing materials and waterproof and
moisture resistant insulating materials. Because of its physiological inertia, in the medical
and health aspects, it can be used to produce artificial organs and medical tubes, and to
prepare raw materials for high-temperature mixing of silicone rubber.
Conditions to avoid: incompatible materials, various sources of heat and sources of
ignition.
Decomposition products: may burn or thermally decompose in the fire to produce carbon
oxides, hydrocarbons, silicon oxides, combustion fumes, and the like.
Polymerization hazard: does not happen
