Epdm rubber strip of ozone resistance, heat resistance, weather resistance, low tender and soft, can be used for the ozone resistance, weather resistance, uv, but based on their structure characteristics, the flame retardancy, oil resistance and poor caking. The chemical structure of ethylene propylene rubber seals vulcanization products with unique performance. A, low density and high filling: epdm rubber seals is a kind of low density, the density of 0. 87. Combined with filling agent, can be added a large number of oil charge and thus can reduce the cost of producing the epdm gaskets, make up for the disadvantage of high price of epdm rubber. Aging resistance: ethylene propylene rubber has excellent weather resistance, ozone resistance, heat resistance, acid and alkali resistance, water vapor, color stability, electronic, oily and normal temperature liquid filling. Epdm rubber strip under 120 ℃ can be use for a long time, under 1 50 ~ 200 ℃ can be temporary or intermittent use. Corrosion resistance: due to the lack of polarity ethylene propylene rubber low unsaturation, polarity of all kinds of chemicals such as alcohol, acid, alkali, oxidant, refrigerant, detergents, animal and plant oil, ketone and fat has good resistance to patience; But the fat and aromatic solvents ( Such as gasoline, benzene and poor stability of mineral oil. Four, resistance to water vapor: ethylene propylene rubber seals has excellent water resistance and superior to its heat resistance. In the 230 ℃ heating steam, nearly 100 h after no change in appearance. The fluorine rubber, silicone rubber, fluorine silicone rubber, butyl rubber, nitrile rubber, natural rubber under the same conditions, significant degradation occur after a short time appearance. Five, a hot water resistance: epdm had hot water resistance is good, also but is closely related to the vulcanization system used. Six, electric performance: epdm gaskets have excellent electric insulation performance and the corona resistance, electric properties better than or close to styrene-butadiene rubber, chlorosulfonated polyethylene, polyethylene and crosslinked polyethylene. Seven, elastic: epdm molecular structure in nonpolar substituent, low molecular cohesive energy, molecular chain can maintain flexibility in a wider range, after natural rubber and butadiene rubber, and can remain in the low temperature.
