Natural rubber NR
(Natural Rubber), with good wear resistance, high elasticity, tear strength and elongation. Advantages: good elasticity, acid and alkali resistance. Disadvantages: not heat-resistant, oil-resistant (resistant to vegetable oil), suitable for making shock-absorbing parts, products used in automotive brake oil, ethanol and other liquids with hydroxide.

SBR styrene SBR
(Styrene Butadiene Copolymer)
Uniform quality, less foreign matter, better wear resistance and aging resistance. Advantages: Low cost non-oil resistant material, good water resistance, and poor compression at high hardness. Widely used in the tire industry, footwear, cloth industry and conveyor belt industry.

Butyl rubber IIR
(Butyl Rubber) Advantages: Good resistance to sunlight and odor. Inner tube, leather bag, rubber paste paper, window frame rubber, steam hose, heat-resistant conveyor belt, etc. for automobile tires.

Hydrogenated nitrile rubber HNBR
(Hydrogenate Nitrile)
Its temperature resistance and weather resistance are much higher than those of ordinary nitrile rubber, and its oil resistance is similar to that of general nitrile rubber. The general operating temperature range is minus 25-150 °C.
Advantages: It has better abrasion resistance than nitrile rubber, and has excellent properties of corrosion resistance, tensile strength, tear resistance and compression.
Widely used in automotive engine system seals.

Ethylene propylene rubber（EPDM）
With good weather resistance and ozone resistance, it has excellent water resistance and chemical resistance. It can be used with alcohols and ketones. It is resistant to high temperature steam and has good impermeability to gases. Widely used in seals or parts of sanitary equipment seals in high temperature steam environment, seals in radiators (car tanks).

Nitrile rubber NBR
(Nitrile Rubber)
The operating temperature range is minus 25-100 °C. Advantages: Good resistance to oil, water, abrasion, solvent and high pressure oil. Good compressibility and elongation. It can be said that it is the most widely used and lowest cost rubber seal.

Neoprene CR
(Neoprene, Polychloroprene)
Good wear resistance, especially good weather resistance, the general temperature range is -50~150 °C.
It is suitable for making all kinds of flame resistant and chemical resistant rubber products that are in direct contact with the atmosphere, sunlight and ozone.
