EPDM gasket

EPDM gasket: 1.good ageing resistance 2.weatherability 3.corrosion-resisting properties Ethylene propylene diene monomer(EPDM)is a rubber processed by combined polymerization of solution of ethane and propene, and tertiary monomer is introduced. EPDM is basically a saturated high polymer. It has very good ageing resistance, weatherability and corrosion-resisting properties.  1.     High ageing resistance: EPDM sealing strip has strong ageing resistance to hot air, can be used at temperatures from 100°C to 120°C for a long time, can keep effective physical properties at temperatures from 140°C to 150°C for a long pull, and can withstand the high temperature at temperatures from 230°C to 260°C within a short time.2. Excellent resistance to ozone: ozone is the main factor causing chap of common rubber. EPDM possesses excellent resistance to ozone and is called “non-chap rubber”. In particular, EPDM is applicable for use in different atmosphere indexes. Compared with (PVC) sealing strip of rubber, EPDM exhibits more obvious advantages. 3. Excellent weatherability means the aging of comprehensive factors of light, heat, freeze, wind, and rain in natural environment, and ozone in the atmosphere. Excellent weatherability means the capability of long-term anti-severe-cold, anti- torridity, anti-desiccation and moisture resistance. EPDM has small contraction in percent, does not deform, and can fully realize the same design life as door, window and curtain wall. 4. Excellent resistance to chemicals. Due to the chemical stability and nonpolarity of EPDM upon itself, EPDM rubber strip does not react with chemicals, does not solve or has small dissolubility among polarity materials. 5. Excellent water fast, over-heat resistant or water vapor resistant properties: EPDM belongs to a macromolecule alkyl anhydrous hydrazine, and possesses “hydrophobicity”. Chemical action between EPDN and water is not easy to take place. 6. Good elasticity and persistent compression resistant property.
