| Macromolecular structure of silicone rubber due to the introduction of a small amount of vinyl can greatly improve the performance of silicone rubber vulcanization process, so in the current application of silicone rubber, most of them contain vinyl. Methyl vinyl silicone rubber is the most common kind of silicone rubber, silicone rubber at home and abroad is currently dominated by the production. In addition it has two general characteristics of methyl silicone rubber, but also a wide temperature range, can be a range of 60 ~ 260 ℃ to maintain good flexibility, it is easier than the dimethyl silicone rubber vulcanization, with a smaller compression deformation, better solvent resistance and the expansion of high-pressure steam stability and excellent resistance to cold, etc., but also because the lower activity of peroxide used for curing, which reduces air bubbles and rubber vulcanization generated when the stability of poor weaknesses. Therefore tends to be used methyl vinyl silicone rubber can be prepared to do the thickness of the larger products. Methyl vinyl silicone rubber silicone rubber is the most widely used species in recent years, a variety of emerging high-performance and special-purpose silicon rubber, mostly based on vinyl silicone rubber-based adhesive, such as high strength silicone rubber, low - compression set silicone rubber, without post-curing silicone rubber, heat-conductive silicone rubber and medical-grade silicone rubber. Methyl vinyl silicone rubber in the aviation industry, widely used as gaskets, sealing materials and fragile, shock protection layer components; in electrical industry can be used for electronic components and other high insulation materials, high temperature potentiometer dynamic seals underground seals long-distance communications equipment; in medicine, due to methyl vinyl silicone rubber on the body's physiological responses to small, non-toxic, it is used for orthopedic surgery, artificial heart valves, blood vessels and so on. |
