Silicone rubber is a special synthetic rubber, places an important position in the rubber family. Because of its special structure, it has excellent performance, such as high resistance, low temperature, high voltage resistance, ozone resistance, radiation resistance, weather resistance, physiological inertia and high air permeability, as well as lubricants and other media show excellent chemistry
Silicone rubber is a linear, high Mr (relative molecular mass) polysiloxane, its Mr generally more than 1.5×105, the molecular backbone consists of silicon atoms and oxygen atoms alternately (-Si-O-Si-), the bond energy of the Si-O bond (422 kJ/mol) is higher than the C-C bond (240 kJ / mol). Silicone rubber is non-toxic and tasteless, and
Silicone rubber has many unique and excellent features, such as high and low temperature resistance, UV resistance, radiation resistance, weather resistance, electrical insulation, high permeability, physiological inertia. Silicone rubber has been widely used in aviation, aerospace, electrical, electronics, chemical, instrumentation, automobile, machinery and other industries as well as medical and health, daily life in various
Silicone rubber is a kind of linear polymer, which is different from other rubber in that its molecular backbone is not composed of interconnected carbon atoms, but by the silicon atoms and oxygen atoms between the composition. Silicone rubber has high thermal stability due to the high bond strength of Si-O, and it has excellent
Rubber compensator has good characteristics of corrosion resistance, anti-vibration, a large compensation quantity, high pressure intensity compensation, market demand is huge. Gas turbine power plant A shortfalls in a gas turbine start intake pipe position has a rubber compensator, due to careless when overhauling burst damage, need within 10 days of maintenance cycle rushed the
When the power tube is radiating, adding insulation layer of insulating media as thermal material between heating element (power tube) and the radiator, such as mica, polyester film, PTFE, etc., this method has some effect, but with the shortages of poor thermal conductivity , mechanical properties. Since only 40% of the rated power can be
Principle The fabric coating of the standard sample was stripped at constant speed. Instrument It is stipulated to use the The constant-rate-of-extension (CRE) testing machine. The movement speed of the testing machine fixture should be 100 ± 10mm/min. The permitted replacement speeds of 50 mm/min and 300 mm/min were agreed upon by the parties concerned.
Silicone rubber coated fiberglass cloth, which the glass fiber cloth as the substrate, coated silicone rubber glass fiber fabric, with single side coating and double sides coating, the coating process is impregnating, rolling, scraping and so on. Silicone rubber coated glass fiber cloth with high tensile strength, stable size, excellent electrical insulation properties and chemical
