Application of EPDM rubber expansion joint.

Nov-22-29
EPDM is a terpolymer of butadiene, non-conjugated diolefins. Diolefins have a unique structure, only EPDM rubber has one of the two bonds can be copolymerized, unsaturated fat hydrocarbon group is mainly done as a cross-chain at.
Excellent aging resistance characteristics, weather resistance, ozone resistance, sunlight resistance, heat resistance, water resistance, water vapor resistance, UV resistance, radiation resistance and other aging properties, in conjunction with other unsaturated diene rubber such as NR, SBR, BR, NBR, and CR and so on, EPDM can play a high antioxidant or antioxidant role.

Because EPDM rubber expansion joint is suitable for the medium of acid and alkali, powerful pipeline, so it is often safe to install and use in the pipeline of lime slurry.
Excellent chemical resistance characteristics, resistance to acids, alkalis, detergents, animal and vegetable oils, alcohols, ketones, etc.; outstanding water resistance, resistance to superheated water, water vapor resistance, oil resistance performance.
Wide range of temperature, EPDM rubber soft connection materials must be selected according to the temperature range, the general 120 ℃ range must be selected EPDM rubber material made of rubber soft connection, the temperature in 120 ℃ -150 ℃ must be made of fluorine rubber material rubber soft connection.
