NR natural rubber manufacturers, who knows Guangdong here, there are manufacturers, a few hair connection is OK

Answer:

Chloroprene rubber (CR) by chloroprene do monomer emulsion polymerization of polymers. This rubber molecule containing chlorine atom, so compared with other general rubber: it has excellent oxidation resistance, ozone resistance, non flammable, after the fire can be self extinguishing, the advantages of oil resistance, solvent resistance, acid and alkali resistance, aging resistance, good air tightness; the mechanical performance is better than natural rubber, so can be used for general rubber, also can be used for special rubber. The main disadvantages are poor cold resistance, large proportion, relatively high cost, bad electrical insulation, easy to stick rolling, easy burning and easy sticking. In addition, rubber poor stability, not easy to save. Temperature range: about 45 DEG C ~100. The main requirements for the manufacture of ozone resistance and aging resistance of high cable sheath and various protective cover, protective cover; oil resistance, chemical corrosion resistance of hose, tape and chemical resistant lining; the underground mining with burning rubber, and a variety of molded products, sealing ring, gasket, binder etc..

Isoprene rubber (IR) is a kind of CIS structural rubber polymerized from isoprene monomer. The chemical composition and solid structure are similar to those of natural rubber, and the properties are very close to natural rubber. Therefore, synthetic rubber is called. It has most of the advantages of natural rubber, anti-aging, because of natural rubber, elasticity and strength than natural rubber slightly lower, poor processing performance, higher cost. Temperature range: about 50 DEG C ~100 can replace the natural rubber production of tires, rubber shoes, rubber hose, tape and other general products.

Polybutadiene rubber (BR) is a cis structure by polymerization of butadiene rubber. The utility model has the advantages of good elasticity and wear resistance, good aging resistance, excellent low-temperature resistance, small heat generation under dynamic load and easy metal bonding. The disadvantage is low strength, poor tearing resistance, poor processability and self adhesion. Temperature range: about 60 DEG C ~100. Usually used in combination with natural rubber or styrene butadiene rubber. It mainly produces tyres, tread, conveyor belts and special cold resistant products.

Butadiene styrene rubber (SBR) copolymer of butadiene and styrene. Performance is close to natural rubber, is the largest yield of general-purpose synthetic rubber, characterized by wear resistance, aging resistance and heat resistance, more than natural rubber, texture is more natural rubber uniform. Disadvantages are: low elasticity, anti bending, anti tear performance is poor; the processing performance is poor, especially the poor, low strength self adhesive rubber. Temperature range: about 50 DEG C ~100. Mainly used instead of natural rubber to make tires, rubber sheets, hose, rubber shoes and other general products.

Natural rubber (NR) is mainly composed of rubber hydrocarbons (polyisoprene), containing a small amount of protein, water, resin acids, sugars and inorganic salts. The utility model has the advantages of large elasticity, high extension strength, high tear resistance and electrical insulation, good abrasion resistance and drought resistance, good processability, easy adhesion to other materials, and superior performance in synthetic rubber in comprehensive performance. The disadvantage is that oxygen and ozone resistance is poor, easy aging, metamorphism, oil and solvent resistance is not good, the first corrosion resistance of acid and base is low, heat resistance is not high. Temperature range: about 60 DEG C ~80. Make tires, rubber shoes, hose, tape, wire and cable insulation and sheath, and other general products. The utility model is especially suitable for making torsional vibration eliminator, engine shock absorber, machine support, rubber metal suspension element, diaphragm and molded product.
