VMQ

Silicone rubber is obtained from silica on silicon as the basis, and the silicon atoms, such as adhesion such as methyl vinyl side chain and the formation of unsaturated polar rubber. The side chain of different causes of silicone rubber with different characteristics. Methyl vinyl silicone rubber (VMQ) is a kind of silicone rubber material used. Silicone rubber has excellent heat resistance, low temperature flexibility and excellent oxidation resistance and ozone resistance, high permeability and gas permeation selectivity. Good electrical insulation properties (bulk resistance greater than 10.Cm breakdown voltage above 30kv/mm), corona resistance and resistance to arc. But the addition of conductive carbon black, nickel powder, aluminum powder, aluminum powder, conductive and appropriate (volume resistance to 5-0.02 Ω.Cm) surface of the silicone rubber can lower, with moisture absorption, can perform the isolation function. Water resistance, but poor water vapor pressure above 50psi, does not recommend the use of. Compatible with most of the oil, chemicals and solvents. General silicone rubber high acid and alkali resistance, solvent resistance can, not resistant to alkanes and aromatic oil. Not recommended for most concentrated solvent, oil, acid and caustic soda in the diluted solution. Special silicone rubber is also resistant to radiation, flame resistance, oil resistance and other properties. The tensile strength of its bottom, wear resistant ability is weak, not normally used to seal.

(one) temperature range

-60 ℃ -225 ℃, special silicone rubber high temperature can reach 300 ℃, and the temperature can be up to -100 DEG C. (TR10 at -100 ℃)

(two) hardness range

Shore A25 degrees to 90 degrees

(three) colour

Black, brown, green, white, red brown, yellow, blue, red, orange, transparent, gray color, can also be specified by the client.

(four) application

Silicone rubber is widely used in modern industry, national defense industry and daily necessities. Can be used in electronic industry of conductive silicone rubber, liquid crystal display the contact piece, TV anode cover, signal transmission cable, wire, electrical connectors, insulation terminal, computer keyboard; silicon rubber heaters, heating tablets can be used to control the precision instrument and oilfield pipeline working temperature. Glass material at room temperature vulcanized silicone rubber adhesive material and filling, sealing material widely used in the construction industry, waterproof bathroom tiles, toiletries, cement joint sealing, sealing silicone rubber can also be used for doors and windows. Sealing electronic parts, electrical fittings potting material, windshield, car doors and windows and body used in the car industry, automatic lifting device of rubber pipe, heating and radiator pipe, high-voltage wire, spark plug cover and a muffler liner, camshaft, valve cover and the tank bottom shell, all kinds of static sealing cushioning and damping products. Silicon rubber as can be tasteless, odorless, non-toxic, so it is very good for materials, household appliances and food industry. In the aerospace, aviation industry is also widely used, such as an oxygen mask sealed switch, waterproof cover, gasket, sealing and shock absorption materials. The silicone rubber has a variety of applications in the field of medicine, including medical equipment seals, implanted and non implanted artificial organs, medical apparatus etc.. Silicone rubber can be used in printing rollers, copier rollers.
