Main Rubber Compounds and Properties
| Rubber material | The performance |
| NBR | 1. The best oil resistance, basic no swelling of nonpolar and weak polar oils 2. Heat oxidation performance is superior to the natural, general rubber styrene-butadiene, etc 3. Has good wear resistance, its wear resistance between 30% and 45% higher than natural rubber 4. Chemical corrosion resistance is superior to natural rubber, but the strong oxidizing acid resistance ability is poor 5. Cold tolerance tensile elastic performance is poor, deformation heat production 6. Electric insulation performance is poor, belong to the semiconductor rubber, should not be used for electrical insulation 7. Ozone resistance is poor 8. Poor processing performance |
| FKM | 1 has excellent high temperature resistant performance (under 200 use for a long time, will undergo more than 300 high temperature short term), is among the highest in rubber material 2. Has good oil resistance, chemical corrosion resistance, can resist the corrosion of aqua regia, also is in rubber material is the best 3. With incombustible, belongs to the self-extinguishing rubber 4. In the high temperature, high altitude performance is better than other rubber, under the air close to the butyl rubber Day 5. Resistant to ozone aging, climate change and the radiation effect is stable |
| SILICON | 1. The high temperature resistance and cold, can be in - 100-300 range of elasticity 2. Resistance to ozone, weather aging resistance performance 3. Good electrical insulating properties, the analysis of the electrical insulation in be affected with damp be affected with damp, water, or smaller at higher temperatures change 4. The hydrophobic surface characteristics and physiological inertia, harmless to the human body 5. Has high permeability, the permeability rate is 10-100 times more than ordinary rubber 6. Poor physical and mechanical properties, tensile strength, tear strength and wear resistance are much lower than the natural rubber and other synthetic rubber |
| HNBR | 1. The nitrile butadiene rubber have better wear resistance 2. And better corrosion resistance, resistance to bulge, tear resistance and compression deformation characteristics 3. Ozone, sunlight and other large oxygen condition with good resistance 4. The product has excellent resistance |
| EPDM | 1. The aging resistance performance is excellent, was regarded as no crack rubber 2. Excellent chemical resistance 3. Excellent resistance to water, hot water and steam resistance 4. Excellent electrical insulation properties 5. Low density and high filling characteristics 6. Ethylene propylene rubber with good elasticity and compression deformation resistance 7. Not resistant to oil 8. Curing speed slow, slower than the general synthetic rubber 3-4 times 9. Self-adhesive and each year are very poor, difficult to process |
