Flexible and elastic silicone rubber has a unique chemical structure that gives it a high temperature resistance and chemical resistance, as no other elastomer, and as a result - it can work in an environment where there can used by any other material. This rubber plate is considerably superior to other elastomers resistance to high temperatures and excel by their durability, have less residual strain and antigezionnymi properties has smell, taste, and is not toxic and has excellent resistance to weathering, so as not be exposed to sunlight, ozone, moisture, dryness. Silicone rubber is solid roll has a smooth, defect-free surface. It is produced in dozens of options hardness of 30 ShA relatively mild to relatively solid 75 ShA. Silicone rubber is solid can have a different chemical composition to impart certain physical properties and cost considerations. Silicone rubber also has good chemical resistance. However, it may swell when exposed to certain solvents, but after evaporation of the solvent, the silicone usually returns to the original size. At these temperatures, the silicone rubber release significantly less gas than other similar elastomers. It burns in an open flame, emitting smoke non-toxic, odorless, and with the formation of white, not conductor of electricity, ash. Silicone rubber itself is universal, in spite of this, there are various modified to operate under special conditions. Current Operating temperature condition of - 60 º C to +320 º C did not significantly affect the physical properties of silicone. Under the conditions of which include high temperature and pressure, requires a general purpose silicone rubber. Permanent deformation is dependent on the operating temperature and pressure, and general-purpose silicone rubber is the most resistant to this phenomenon. When there is contact with the fuel or solvent, the best choice is a fluorinated silicone rubber.
