Methyl Vinyl Silicone Rubber CAS NO.67762-94-1
Name:Methyl Vinyl Silicone Rubber
CAS No.:67762-94-1
Appearance: colorless transparent
Molecular formula: RMe2SiO(Me2SiO)n(MeViSiO)mSiMe2R(R：Me、Vi)
Relative density (water=1): 0.97
Boiling point: 205℃
Methyl vinyl silicone rubber is copolymerized by dimethyl siloxane and a small amount of vinyl siloxane, and the vinyl content is generally 0.1%~0.3% (molar fraction). The introduction of a small amount of unsaturated vinyl makes the vulcanization process and finished product properties, especially heat aging resistance and high temperature compression deformation resistance, greatly improved. The content of methyl vinyl siloxane units has a great influence on the vulcanization and the heat resistance of the vulcanizate. If the content is too small, the effect will not be significant. If the content is too large (up to 0.5% (molar fraction)), the resistance of the vulcanizate will be reduced hot sex.
use:
It is widely used in the replacement of high and low temperature sealing pipes, gaskets, rollers, key rubber rollers, and porcelain insulators.
