Methyl Vinyl Silicone Rubber Introduction

Methyl Vinyl Silicone Rubber (Silicone Gum) is a high molecular polysiloxane compound synthesized with high-quality siloxane and vinyl. This series can be divided into two major categories: methyl-terminated and vinyl-terminated. Series 110 are vinyl-terminated methyl vinyl silicone gum, and Series 112 are methyl-terminated methyl vinyl silicone gum.

Methyl Vinyl Silicone Rubber (Silicone Gum) are elastomers formed at high temperature after reinforcing agent (silicon dioxide) and additive are added and can be used to manufacture various silicone rubber compound products such as silicone rubber for molding, silicone rubber for extrusion, electrical insulating silicone rubber and flame retardant silicone rubber and further manufacture various silicone rubber products.
Product NameRS-110 Methyl Vinyl Silicone Rubber (Silicone Gum)
PropertiesRS-110 Silicone Rubber 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.
UsesIt 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 material for high temperature silicone rubber.
PackageNet weight 25kg/carton (plastic-lined paperbox).
StorageStore in a cool, dry, well-ventilated area away from strong oxidizing agents. Avoid to contact alkalis and acids substances and lead; It is non-hazardous substance.
HandlingBe careful when loading and unloading to avoid damages of the package. During transporting, protect against damp, water, acid and alkali.

Methyl Vinyl Silicone Rubber: Guide

RS-110 Methyl Vinyl Silicone Rubber, referred to as Vinyl Silicone Rubber, RS-110 silicone rubber is a copolymerization of dimethicone and a small amount of vinyl silicone, vinyl content is generally 0.03% to 5.0% (can be customized). 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 performance has been greatly improved.

The content of methyl vinyl siloxane unit has a great influence on the vulcanization performance and heat resistance of the vulcanized rubber, too little effect is not significant, too much [more than 0.5% (mole fraction)] will reduce the heat resistance of the
