Natural rubber (NR) is mainly composed of rubber (polyisoprene), which contains a small amount of protein, water, resin acids, carbohydrates and inorganic salts. The utility model has the advantages of high elasticity, high tensile strength, good tear resistance and electrical insulation, good abrasion resistance and drought resistance, good workability and easy bonding with other materials. The disadvantage is that oxygen and ozone resistance is poor, easy aging deterioration; oil and solvent resistance is not good, the corrosion resistance of the acid and alkali resistance is low. Production of tires, rubber shoes, rubber hose, rubber belt, wire and cable insulation and sheath as well as other common products. Especially suitable for the manufacture of torsional vibration eliminator, engine shock absorber, machine bearings, rubber metal suspension components, diaphragm, molded products.

Styrene butadiene rubber (SBR) copolymer of butadiene and styrene. Performance is close to natural rubber, is the largest production of synthetic rubber, which is characterized by wear resistance, aging resistance and heat resistance than natural rubber, texture is also more uniform than natural rubber. Disadvantages are: low elasticity, anti bending, anti tear performance is poor; the processing performance is poor, especially the poor, low strength self adhesive rubber. Mainly used to replace natural rubber tire, rubber hose, rubber plate, making shoes and other general products.

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 disadvantage is that the cold resistance is poor, the proportion is large, the relative cost is high, the electrical insulation is not good, and the process is easy to stick, easy to scorch and easy to stick. In addition, rubber poor stability, not easy to save. 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..

Ding Ji rubber (IIR) is the copolymer of isobutylene isoprene or butadiene and a small amount of. The biggest feature is good air tightness, ozone resistance, aging resistance, high temperature resistance, long working temperature is below 130 DEG C; ability of inorganic acid (such as sulfuric acid, nitric acid) and organic solvents, absorbing vibration and damping characteristics of good electrical insulation is also very good. Disadvantages are poor elasticity, poor processing performance, slow curing speed, adhesion and poor oil resistance. Mainly used for tyre, tyre, water balloon, wire and cable insulation, chemical equipment lining and shockproof products, heat resistant conveyor belt, heat aging of adhesive tape products.

Ding Qing rubber (NBR) butadiene and acrylonitrile copolymer. The utility model is characterized in that the performance of the gasoline and the aliphatic hydrocarbon oil is particularly good, which is better than that of polysulfide rubber, acrylic ester and fluorine rubber. Good heat resistance, air tightness, wear resistance and water resistance are good, strong bonding force. The disadvantage is that the cold resistance and ozone resistance is poor, the strength and the elasticity is low, the acid resistance is poor, the electrical insulation is not good, and the polar solvent resistance is poor. Mainly used in the manufacture of a variety of oil products, such as hose, sealing products, etc..

Ethylene propylene rubber (EPM\\EPDM) copolymer of ethylene and propylene, generally divided into two EPDM and three epdm. Characterized by ozone resistance, UV resistance, weather resistance and excellent aging resistance, ranking first in the general rubber. Electrical insulation, chemical resistance, impact elasticity is very good, acid and alkali resistance, the proportion of small, can be filled with high. Heat up to 150 DEG C, solvent - ketone and ester, but not resistant to aliphatic hydrocarbon and aromatic hydrocarbon, and other physical and mechanical properties of natural rubber and is slightly inferior to styrene butadiene rubber. The disadvantage is that the viscosity and viscosity are very poor, not easy to glue. Mainly used as chemical equipment lining, wire and cable sheath, steam hose, heat-resistant conveyor belt, automotive rubber products and other industrial products.

Silicone rubber (Q) is a kind of special rubber containing silicon and oxygen atoms in the main chain. Its main characteristic is high temperature resistant (up to 300 DEG C) and low temperature (minimum -100 C), is currently the best cold, high temperature resistant rubber retainer AI; at the same time, excellent electrical insulation, stability of thermal oxidation and ozone high chemical inertness. The disadvantage is the low mechanical strength, oil resistance, solvent resistance and acid and alkali resistance is poor, difficult to cure, the price is more expensive. Mainly for the production of high and low temperature products (hose, seals, etc.), high temperature resistant wire and cable insulation, due to its non-toxic and tasteless, also used in food and medical industry.

Fluorine rubber (FPM) is a kind of organic elastomer which is made up of fluorinated monomers. The characteristics of high temperature resistance of 300 DEG C, acid and alkali resistance, oil resistance is the best oil resistant rubber, anti radiation, high vacuum performance; electrical insulation, mechanical properties, chemical resistance, ozone resistance, ageing resistance was good. The disadvantage is the poor workability, high price and poor cold resistance, low elastic permeability. The utility model is mainly used for the vacuum, high temperature resistant, chemical resistant sealing materials, rubber hoses and other parts and the automobile industry of the aircraft and rocket made in the national defense industry.
