EPDM Advantage:

(1)Epdm: density (1,200-1,350) KG/M3. Excellent aging resistance, good chemical resistance, good impact elasticity. In 100 PPHM medium containing ozone, 2430 hours without cracking;

(2)low density and high packing: epdm is a kind of rubber with low density, and its density is 0. 8 July. In addition, it can be filled with a large amount of oil and filler, thus reducing the cost of rubber products, making up for the high price of epdm raw rubber, and for epdm with high Mooney value, the reduction of physical and mechanical properties after high filling is not large;

(3)aging resistance: epdm has excellent weather resistance, ozone resistance, heat resistance, acid and alkali resistance, water vapor resistance, color stability, electrical performance, oil filling and room temperature fluidity. Epdm products under 1 20 ℃ can be use for a long time, in 1 50 ~ 200. C can be used briefly or intermittently. Adding suitable anti - aging agent can increase its service temperature. Epdm crosslinked with peroxide can be used under more stringent conditions;
Epdm at ozone concentration 50 10 ~, stretch 30%, can reach more than 1 50 h without cracking.

(4) corrosion resistance: due to the lack of polarity of ethylene and propylene rubber, low degree of unsaturation, so all kinds of polar chemicals such as alcohol, acid, alkali, oxidant, refrigerant, detergent, animal and vegetable oil, ketone and fat have good resistance; However, it is less stable in aliphatic and aromatic solvents such as gasoline, benzene and mineral oils;
The performance will also decrease under the long-term action of concentrated acid. ISO/TR7620 compiles data on the effects of nearly 400 corrosive gaseous and liquid chemicals on various rubber properties. There are more than 80 kinds of grade 1 chemicals of ethylene - propylene rubber (epdm);

(5)water vapor resistance: ethylene propylene rubber has excellent water vapor resistance and better than its heat resistance.
In the 230 ℃ heating steam, nearly 1 00 h after no change in appearance. Under the same conditions, fluorine rubber, silicone rubber, fluorine silicone rubber, butyl rubber, nitrile butadiene rubber and natural rubber experienced obvious deterioration in appearance after a short time;
