Property of raw material:NR,CR,SBR,EPDM,SLICONE,FKM,NBR
(Natural Rubber) is made by latex from the rubber tree collection. Natural rubber is the polymers of isoprene. It has good abrasive resistance, high elasticity, tensile strength and elongation. Easy to aging in the air, become sticky when exposed to heat.It is easy to expand and dissolve in mineral oil or gasoline. It is able to bear alkali, but not strong acid.
Advantages:
1). good elasticity;
2). resistance to acid and alkali;
Disadvantages:
1). no weather resistance;
2). no oil resistance (but vegetable oil resistant);
Applications:
1). the raw materials of rubber belts, rubber hoses, rubber overshoes;
2). for the production of shock absorber parts;
3). used in the liquid with a hydroxyl automotive brake fluid, ethanol and other products;
(Ethylene Propylene Rubber) is made by the co-polymerization of ethylene and propylene, and therefore heat resistance, anti-aging resistance, ozone resistance, stability are very good. But sulfur cannot put into sulfur. In order to solve this problem, EP backbone introducing a small amount of a third component of the double-stranded and can add sulfur serve EPDM, the general temperature of -50 ~ 150 °C. It has excellent resistance to polar solvents such as alcohols, ketones and so on.

7). soluble in benzene, toluene, xylene, ethyl acetate, chloroform and other solvents;
Disadvantages:
1). not recommend to use strong acid, ozone, oils, ester oils and fats, and most of the hydrocarbons;
2). high hardness degrees with poor compressibility;
3). ozone resistance is poor
Applications:Â
 Widely used in the tire industry, footwear, cloth industry and conveyor industries.
(Neoprene, Polychloroprene) is made by the polymerization of monomers from chlorine-butene. Rubber elastic resistance is good after vulcanization. It is not afraid of direct exposure to sunlight, particularly good weather resistance, not afraid of intense distorted, not afraid of refrigerating fluid, resistance to acid resistance, silicon ester lubricants, but the impatience of phosphate-based hydraulic oil. Easy to crystallize at low temperatures, hardening. Storage stability is poor at low aniline point mineral oil expansion volume. General temperature range of -50 ~ 150 °C.
Advantages:
1). good elasticity character;
2). good compression character;
3). the recipe does not contain sulfur, so it is easy to make;
4). it resists to vegetable oils and animal oils;
5). neutral chemicals, fats, oils, various oils and solvents will not impact on physical  properties;
6). with flame-proof properties;
7). resistance R12 seals of refrigerating fluid;
Disadvantages:
not recommend to use of a strong acid, nitro hydrocarbons, esters, ketones, chloroform and chemicals into the system
Applications:
1). rubber parts or seals on appliances;
2).suitable for the production of direct touch with the atmosphere, sunlight, ozone components;
3). for a variety of fire resistant, chemical resistant rubber products;
