About EPDM o ring

EPDM rubber is made of Ethylene, propylene and butadiene, the highest working temperature of EPDM: 130?

    EPDM Hydraulic rubber o ring anti-acid performance: excellent

    EPDM Hydraulic rubber o ring anti-alkali performance:excellent

 EPDM Hydraulic rubber o ring is acidproof alkali, corrosion resistance. Because EPDM rubber is lack of polarity, It has a better resistance for alcohol, acid, alkali, oxidant, refrigerants, cleaning agents, dynamic plant oil, ketone and ester; but in fat and aromatic is a solvent (such as poor stability in mineral oil and gasoline, benzene and so on). And its performance will increase if it is effected by concentrated acid for a long time. The ISO/TO 7620 has collected of nearly 400 kinds of working results of corrosive gas and liquid chemicals make a variety of rubber materials. It stipulates 1-4 levels to show the degrees.  The effect of corrosion chemicals for rubber performance: level, volume, expansion ratio, hardness decrease rate. ??

    Two advantages of EPDM Hydraulic rubber o ring: excellent ozone resistance, oxygen resistance.With high strength, high pressure resistance, EPDM rubber hydraulic O-ring in 120 DEG C can be used for a long time, in the 150 to 200 DEG C can be transient or intermittent use. Adding suitable antioxidant can improve the use of temperature. Oxygened  EPDM Hydraulic rubber o ring can be used under harsh conditions. EPDM hydraulic O-ring can be not cracking in ozone concentration 50pphm, stretching 30%, more than 150h.

   Above all, wonderful raw material.
