Epdm is one of the most commonly used rubber material for a rubber expansion joint. Comparing to other rubber materials, epdm has following superiors:
sufficient stock of rubber expansion joint
1.High cost effective, lightest raw rubber density in common rubber, only 0.86-0.90kg/m³.
2.Excellent aging resisting performance, resistant to weather, ozone, sunlight, heat, water, ultraviolet ray and radiation, when matching use with other unsaturated rubber like NR, SBR, BR, NBR and CR, epdm has function of macromolecule antioxidant or anti-aging agent.
3.Excellent chemical medicine resistance, resistant to acid, alkali, scouring agent, animal and vegetable oil, ketone, etc.. Excellent water proofing, resistant to hot water, water steam and polarity oil.
4.Excellent insulating property, volume resistivity is 1016Q·cm, breakdown voltage is 30-40MV/m, dielectric constant is (1kHz, 20℃)2.27.
5.Wide application range, min using temperature is -40 to -60℃, it can long-time use under 130℃.
When epdm is used as the rubber expansion joint material, epdm expansion joint is especially suitable for high temperature and acid-base working environments. The epdm expansion joints have been successfully applied in piping systems to reduce noise, relieve movement stresses, isolate vibration, compensate misalignment and accommodate pressure loads. Epdm rubber expansion joint helps to lengthen the service life of pumps and other equipments. Due to its excellent performance, epdm rubber expansion joint are welcomed in power plants, municipal engineering projects and so on.
