Ethylene Propylene Rubber-EPDM/EPM

Ethylene propylene rubber is a synthetic rubber with ethylene and propylene as the main monomer, according to the different composition of the monomer in the molecular chain, there are binary ethylene propylene rubber(EPM) and tertiary ethylene propylene rubber(EPDM).

Quantity:

Ethylene Propylene Rubber – EPDM/EPM


The main performance advantages of EPDM are as follows.


(1) High cost performance, with a raw rubber density of only 0.86-0.90g/cm3, which is the lightest common rubber with raw rubber density; and it can be bottled in large quantities to reduce rubber costs.


(2) Excellent aging resistance, weather resistance, ozone resistance, sunlight resistance, heat resistance, water resistance, water vapor resistance, UV resistance, radiation resistance and other aging properties. When EPDM is used in combination with other unsaturated diene rubbers such as NR, SBR, BR, NBR, CR, etc., it can act as a polymer antioxidant or anti-aging agent.


(3) Excellent chemical resistance, acid, alkali, detergent, animal and vegetable oils, alcohol, ketone, etc.; excellent water resistance, superheated water, water vapor resistance; polar oil resistance.


(4) Excellent insulation performance, volume resistivity 1016Ω-cm, breakdown voltage 30-40MV/m, dielectric constant (1kHz, 20℃) 2.27.


(5) Wide operating temperature range, minimum operating temperature -40-60℃, can be used for a long time below 130℃.


Hirsch Rubber exports EPDM/EPM to 15 countries including the United States, Russia, Brazil, Argentina, South Korea, Germany, Italy, Spain, Australia, and India.
