Guangdong silicone rubber with silica powder prices where good

I. Overview of the silicone gel used Silica: Silica silicone sealant with a choice of a white powder ultrafine inorganic mineral raw natural quartz ore by crushing, pickling, grinding, drying, grading refining process. With high brightness, high permeability sense, good leveling dispersion, low oil absorption, uniform particles. And it has a compressive strength, tensile strength, impact resistance, wear resistance, corrosion resistance, chemical and physical properties and stability characteristics. Second, our product specification sheet: Silicone rubber with silica powder Specification 400 mesh 600 mesh 800 mesh mesh 1250 1000 1500 4000 2000 mesh mesh mesh mesh 8000 6000 10,000 head Head III silicone rubber with Silica main features: 1, Silica is a very stable chemical and physical neutral inorganic fillers, non-crystalline water does not participate in the curing reaction does not affect the reaction mechanism. 2, to improve the shape of powder, the specific surface area increases, increasing the contact surface with the adhesive, improve the mechanical strength of 3, the filling factor can be increased, reduced shrinkage and coefficient of linear expansion of the cured product upon curing. 4, can reduce the amount of heat curing, and extend the construction period. 5, filling increase, cured density, hardness, compressive strength, tensile strength, impact resistance and other mechanical strength is increased and wear resistance. 6, to increase the amount of filler reduces the production cost of the adhesive. Fourth, Ying Feng production of silicone rubber silica powder is widely used in several industries: a silicone rubber applications in the construction industry: Silicone Building Sealant in high-rise construction material feedstock plays an important role. It has occupied a strong position, use in expanding the bottle is increasing, the amount also increased, has become a major manufacturer of silicone main varieties. Silicone sealant is durability, reliability is very good common-grade sealing materials, mainly used for sealing and bonding window glass cabinet grid slots firmly, bonding and sealing glass curtain wall, glass seams, bathroom , bathroom countertops, sanitary seal, wainscoting, railings and other joints sealing, roads, bridges, airports fill in the blank concrete pavement expansion joint seals. Second, the automobile industry applications: Silicone sealing materials because of their unique heat cold, the amount used in the engine system, exhaust system, fuel system, is also increasing. It is mainly used for in situ molding. In order to meet the requirements of various sealing parts, the development of a variety of performance products. Mainly used engine oil pan and transmission seal, axle combination of surface seal, engine valve cover seals, car mats screen printing micro seal, car headlights and taillights formation package, windshield seals. Third, the application in the electrical and electronic industries: the silicone sealant used in electrical and electronic aspect is also very broad, household appliances, electronic equipment, communications equipment and other essential materials. Mainly used for color TV assembly line, and other electronic printed circuit basic form of fixed and caulking, adhesive seal lighting equipment, potting coupling seal cable, high-voltage transformers, high voltage thick-film resistors and other electronic components, coating and so on.
