Grey Htv High Temperature Vulcanized Electric Insulated Silicone Rubber for Composite Insulator

Product DescriptionHigh temperature vulcanized silicone rubber is a high molecular weight (molecular weight is generally 400,000 ~ 800,000) of polysiloxane (namely raw rubber) with reinforcing filler and other additives, using organic peroxide as curing agent, by pressure molding (molding, extrusion, calensing) or injection molding, and at high temperature cross chain into rubber. This rubber is commonly referred to as silicone rubber for short.High temperature vulcanization of silicone rubber is generally divided into two stages, the first stage is the silicon raw rubber, reinforcing agent, additives, curing agent and structure control agent mixing, and then the mixing material in the metal mold pressure heating molding and curing, the pressure is about 50 kg /cm2, the temperature is 120 ~ 130ºC, the time is 10 ~ 30 minutes, The second stage is to remove the silicon rubber from the mold, put it in the oven, at 200 ~ 250ºC for a few hours to 24 hours. The rubber is further vulcanized, and the organic peroxide is decomposed and volatilized.        The reinforcing filler of silicone rubber is various types of white carbon black, which can increase the strength of vulcanized rubber by ten times. Adding various additives is mainly to reduce the cost of rubber, improve the properties of rubber and give vulcanized rubber various special properties such as flame retardant, conductive and so on. Cross-chain agents are a variety of organic peroxides, such as benzoyl peroxide,2, 4-dichloroyl peroxide, diaqueryl peroxide,2, 5-di-butylperoxyhexane, etc. Structure control agent is in order to avoid the mixing material placed for a long time, the "structure" to make the rubber harder and harder, difficult to process and mature and added, can use methyl hydroxyl silicone oil or diphenyl dihydroxyl alkane as structure control agent.The side groups on the main chain of silicone rubber can be methyl, ethyl, vinyl, phenyl, trifluoropropyl and so on. Methyl groups are most commonly used, but other groups can also be introduced to improve machining properties and other properties. Therefore, according to the different side group and adhesive formula, you can get a variety of different uses of silicone rubber, generally can be divided into the following types: general type (including methyl and vinyl), high temperature and low temperature type (including phenyl, methyl and vinyl), low compression permanent deformation (including methyl and vinyl), low shrinkage (to volatile) and solvent resistance (fluorine silicone rubber).BrandAppearanceDensityHardness(Shore)Tensile Strength(Mpa)Extensibility %Tear strength (KN/M)Linear shrinkage rate %Rebound elasticity %Vulcanizing agent2263white1.4504.525013\double 2.5Test Report  Company ProfileWuhan Line Power Transmission Equipment Co., Ltd. is mainly engaged in the research ,development,production and sales of high voltage transmission power composite insulator series products.The core technology comes from the scientific and research institutions such as Wuhan University (originally Wuhan University of Water and Electricity),Hubei Institute of Chemical and Industry and Wuhan High Pressure Research Institution and so on.In order to adapt to the industry development demands,it was reformed in combination with national capital by the scientists and engineers who are in the field of composite insulator.Now it is restructured as a new modernized enterprise which integrates research ,production, marketing and sales. The company had formed a series of composite insulator mature products at the beginning of its establishment. These products have been widely used in power, railway and other industries for many years.The core team members of company technology, production and management have more than 20 years of working experience in the same industry.
