CM rubber

The application research of CM rubber
CM special rubber rubber is a kind of environmental protection, it has low Mooney viscosity, non-crystalline sex, processing performance is good wait for a characteristic, has excellent cold resistant, aging resistant, resistant to ozone, oil resistant and flame retardant properties, mainly used in wire and cable, rubber hose, conveyor belt, rubber dam, car inner tubes, moulded rubber products, waterproofing materials and other products production, has the very good economic and social benefits.
CM rubber are transparent white flake, Mooney viscosity of 35-65, volume resistance for the q - 1012-1014 CM, glass transition temperature between - 30 ℃ to 50 ℃, in - 30 ℃ to 120 ℃ can be use for a long time, without flame retardant when chlorine content index of 25% to 25%.
The characteristics of CM rubber:
1, the molecular structure of polarity chain segment and nonpolar segments, all kinds of high polymer material (polar and nonpolar plastic or rubber) has good compatibility.
2, due to the structure of molecular chain saturated, has excellent weather resistance, ozone resistance, chemical resistance and heat aging properties.
3, good oil resistance, and flame retardancy.
The application of CM rubber:
1, CM has excellent heat resistant, oil resistant, resistant to flexible, flame retardant, such as performance, made of liquid pipelines, oil and gas pipelines is superior to other synthetic rubber, especially for confined liquid delivery hose has unique advantages. Now abroad has been widely used in production of steel wire winding, weaving hose.
2, CM also has excellent heat resistance, ozone resistance, resistance to atmospheric aging, cold resistant, flame retardant, flexing, therefore, is also a conveyor belt production industry optimization, for the production of flame retardant conveyor belt, heat resistant conveyor belt, the common conveyor belt, etc.
3, CM can be used to make wire and cable, hose, sealing materials, washer, machine parts and flame retardant conveyor belt, etc. Because of its cost is lower than nitrile rubber, neoprene, in CM rubber as basic material of wear resistance, dielectric properties of vulcanizate properties, heat resistance, aging resistance, oil resistance, etc is superior to the neoprene, with ethylene propylene rubber, natural rubber, isoprene rubber and nitrile rubber, most used in wire and cable industry and the automotive industry (mold products and extrusion products), etc. CM rubber has been widely applied in the field of wire and cable. Using its flame retardant, good heat resistance, weather resistance, can be applied to air conditioning, elevators, electric welding machine, such as cable sheath.
4 CM, filling ability of ferrite magnetic powder is high, with CM all kinds of magnetic components made of rubber, precision flexible, good low temperature performance, widely used in computer, automotive, home appliances, electrical, medical, education industry.
5, CM rubber has significant cost advantages, it can be with epdm, nitrile, butyl benzene, chloroprene rubber, natural rubber and other. Besides can reduce costs, the key can make up for some defects and the insufficiency of rubber, its ideal and used for epdm, nitrile rubber, styrene butadiene, neoprene.
