#fumed #silica #suppliers <br>Name: <br>Methyl Vinyl Silicone Rubber <br> <br>Feature: <br>High temperature resistant <br> <br>Appearance: <br>Methyl vinyl silicone rubber is colorless and transparent, with no obvious mechanical impurities. <br> <br>Description of Methyl Vinyl Silicone Rubber <br>Methyl vinyl silicone oil, 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. <br> <br>Features of Methyl Vinyl Silicone Rubber <br>As one of the professional silicone rubber suppliers, Zhongtian provides exceptional performance Methyl Vinyl Silicone Rubber that make it ideal for industrial applications. Here are some characteristics of vinyl methyl silicone: <br> <br>1.High and low temperature resistance, can work under -50~250℃ for a long time. <br>2. Moisture resistance, electrical insulation, arc resistance, corona resistance. <br>3. Aging resistance, ozone resistance. <br>4. Non-stick surface and water repellent. <br>5. Small compression deformation and saturated steam resistance. <br> <br>Application of Methyl Vinyl Silicone Rubber <br> <br>ZT-110 Methyl Vinyl Silicone Rubber can be widely used in various fields of silicone compounds including silicone rubber for molding and for extrusion. <br> <br>It basically mixed with fillers and additives, and then after molding, extrusion, injection, etc. sulfide into articles. By incorporating the process of mixing silicone rubber, manufacturers can tailor the material to meet specific requirements for various applications. <br> <br>Silicone rubber mixed products have the properties of excellent resistance to high temperature. <br> <br>Package of Methyl Vinyl Silicone Rubber <br>N.W. 25kgs/carton <br>Provide customers&#039; packing <br> <br>Transportation of Methyl Vinyl Silicone Rubber <br>Prevent rain or sun exposure <br> <br> <br> <br>[a]https%3A%2F%2Fwww.zteastsilicone.com%2Fproducts%2Fmethyl-vinyl-silicone-rubber.html[/a]
