Description of Methyl Vinyl Silicone Rubber
Methyl vinyl silicone rubber, referred to as vinyl silicone rubber, is made of dimethylsiloxane and a small amount of vinyl siloxane copolymerization, vinyl content is generally 0.1% to 0.3% (molar fraction). The introduction of a small amount of unsaturated vinyl makes its vulcanization process and the performance of the finished product, especially heat aging resistance and high temperature compression deformation resistance has been greatly improved. The content of methyl vinyl siloxane unit has a great influence on the vulcanization and heat resistance of the vulcanized rubber, too little is not significant, too much [up to 0.5% (molar fraction)] will reduce the heat resistance of the vulcanized rubber.
Features of Methyl Vinyl Silicone Rubber
1.High and low temperature resistance, can work under -50~250ºC for a long time.
2. Moisture resistance, electrical insulation, arc resistance, corona resistance.
3. Aging resistance, ozone resistance.
4. Non-stick surface and water repellent.
5. Small compression deformation and saturated steam resistance.

Application of Methyl Vinyl Silicone Rubber
ZINCA110 Methyl Vinyl Silicone Rubber can be widely used in various fields of silicone compounds including silicone rubber for molding and for extrusion.
It basically mixed with fillers and additives, and then after molding, extrusion, injection, etc. sulfide into articles.
Silicone rubber mixed products have the properties of excellent resistance to high temperature.
