| Material | Character | Shore A hardness | Application |
| NR | Natural rubber has good elasticity, air tightness and insulation properties, excellent flexural resistance, low heat generation, low hysteresis loss.It has good processing performance, the disadvantage is poor oil resistance, alkali resistance, weather resistance and solvent resistance, and strong acid resistance. | 40-90 | Can be used to manufacture tread, inner tube, etc., can also be used to manufacture rubber hose, tape, general mechanical sealing ring, sponge products, medical products, latex products, etc |
| NBR | Oil resistance, benzene resistance, hydrocarbon resistance and aging resistance.With the increase of acrylonitrile content, the properties of oil resistance, benzene resistance, wear resistance, heat resistance, hardness and tensile strength of NBR are improved, while the properties of resilience, low temperature flexure resistance and compression permanent deformation are decreased. | 40-90 | Manufacturing oil-resistant rubber products, also widely used in molding products, pressed products, sponge products, asbestos products, wire and cable cover rubber, adhesive and building materials. |
| HNBR | Prepared by catalytic hydrogenation of nitrile butadiene rubber.It has excellent heat resistance, ozone resistance, high energy radiation resistance, oil resistance, alkali resistance, oxidant resistance and other properties.Excellent mechanical properties. | 40-90 | Mainly used in automobile, mechanical engineering, petroleum and other industries.In the petroleum industry, we manufacture pump and engine fixings, drill pipe protective sleeves, valves, wellhead seals, etc. |
| EPDM | It has good heat resistance, ozone resistance, climate resistance, chemical stability, low temperature resistance, dielectric properties, etc.Ethylene propylene rubber can withstand a wide range of media, including polar solvents (such as ketone esters), hot water and 200 ° C water vapor (no air). | 40-90 | Applied to automotive diaphragm, leather bowl, dust-proof rubber sleeve, brake parts and seals, rubber hose, etc.Can also make a variety of chemical corrosion resistant products. |
| CR | It has excellent solvent resistance and oil resistance, as well as excellent acid and alkali resistance, climate aging resistance, ozone aging performance, crystallization, good water resistance, air resistance is only worse than nitrile rubber. | 30-90 | Manufacture heat-resistant wire and cable sheath, oil-resistant rubber products, automobile oil resistant rubber hose, acid and alkali resistant rubber products, weather resistant aging rubber products, flame retardant rubber products, all kinds of sealing gaskets. |
| IIR | Excellent heat aging performance, with good ozone aging resistance, climate aging resistance and chemical stability, corona resistance and electrical insulation, as well as good water resistance, water permeability is very low. | 30-80 | All kinds of mechanical products, vibration isolation parts, waterproof sheets for construction, sealing and caulking materials. |
| FKM | Excellent high temperature resistance, can be used at 200℃ for a long time, 300℃ for a short period of use.Fluorine rubber has excellent vacuum resistance, resistance to strong acid, high concentration of hydrogen peroxide and strong oxidant, resistance to a variety of organic solvents and various oils, resistance to excessive hot water and steam, resistance to climate aging and ozone aging, resistance to moderate dose radiation, flame retardant. | 50-90 | Used for automotive engine sealing, aircraft engine sealing, also suitable for other high-temperature sealing occasions.Applied to aerospace aircraft, oil exploration Wells and so on. |
| FVMQ | The substitution of the methyl side chain on the main chain of the organosilicon material by fluorinated groups not only maintains the high and low temperature resistance, climate resistance and ozone aging, electrical insulation, flame resistance, non-toxic, physiological inertia, but also gives the oil resistance, solvent resistance and chemical resistance.Good tolerance to aromatic, aliphatic, fuel oil, lubricating oil, hydraulic oil, etc. | 30-80 | Used in military industry, automotive parts, petrochemical, medical and health and electrical and electronic products. |
| Silicone | Silicone is a soft, transparent, highly elastic material that can be used for a long time in the range of -100 ° C to +300 ° C, and is not prone to cracking and deformation, and does not produce viscosity and adhesion. | 20-90 | Widely used in a variety of food grade industry, household appliances, auto parts, medical equipment and other products sealing and waterproofing. |
