It can not dissolve in water, but dissolve in organic solvents such as methyl benzene, etc. It has excellent properties such as small compression deformation, resistance to saturated vapor pressure. It can be used in manufacturing sealing material resisting to high and low temperature, waterproof, moisture- resistant and insulation material in aviation, mechanical, chemical industry, etc. Due to its physiological inertia, it can be used to manufacture artificial organ and medical rubber pipe in medical fileds, as well as raw materials for high temperature silicone rubber.
