Common Material Physical Performance and Appication
| Material | Characteristic | Working Temperature (℃） | Application |
| NR | Good resistance to abrasion, rebound, tear and elongation. It`s suitable for use in hot and cold water, ammonia, ethylene glycol, dilute acids and alkalis. But it`s easy to aging in air, stickiness by heat, inflation and dissolved in minaral oil & gasoline. | -50～70 | Used in rubber belt, rubber tube, rubber strip. Products always be used in –OH liquid ( for example, auto brake oil and alcohol). |
| NBR | Excellent resistance to oil, heat, abrasion, aliphatic-solvent and high voltage oil. But not suitable for use in polar solven, such as ketone, ozone, nitro-hydrocarbon, chloroform. | -40～120 | Used in fuel tank, grease-box and products always be used in following medium: mineral oil, gasoline, water, silicone grease, silicone oil, Second ester lubricating oil, Ethylene glycol series hydraulic oil etc. |
| HNBR | Better resistance to abrasion, corrosion, tension, tear, compression set. It`s suitable for use in ozone, sunshine and other atmospheric conditions. But not suirable for alcohol, esters and aromatic liquid. | -40～150 | Used in air-condition freezer, especially be widely used in R134 a system and auto engine system. |
| VMQ | Excellent resistance to heat, cold, ozone, aging. And good electrical insulation property. Bad tensile strength and poor resistance to abrasion, oil. | -60～230 | Used in household appliance industry, food Processing Machinery Industry and the sealing which contact with body. |
| EPDM | Excellent resistance to weather, aging, ozone, and Strong Chemical Stability. Even excellent resistance to freon and various refrigerants. | -50～150 | Used in high-temperature water vapor, sanitary ware, refrigerator etc. |
| FKM | Excellenet resistance to high temp., chemical, most of the oil and solvent. Poor resistance to cold. | -20～220 | Used in special working condition ( high temp. chemical corrosion,oil etc), and be widely used in metallurgy, chemical industry, automobile, electric power etc. |
| IIR | Good impermeability to universal gas, good resistance to sunshine, ozone, animal & vegetable oil and Oxidizable chemicals. | -55～100 | Used in making parts which have good resistance to chemicals and vacuum equipment. |
| CR | Good elongation, good resistance to abrasion, aging, rebound, and fire. | -40～100 | Used in making parts which touch in atmosphere, sunshine, ozone directly, and resistance to fire, abrasion. |
