The difference between PU foam seal and traditional seal is as follows. Advanced chlorosulfonated polyethylene; Or acrylonitrile - butadiene rubber and thermoplastic rubber (TPE) 1) Santoprene ® ozone can 2), foam sealing strip resistance to ultraviolet optical properties, chemical solvents, wide working temperature range (60 ° c to 135 c); Tears of 3) has a strong, good tensile patience can, between the site USES a temperature of 150 ℃ to 10 ℃ after millions of Flex without cracking; 4) return to the original shape after rapid compression, even if the original soft is maintained in the harsh environment; 5) green rubber compound rubber, non-toxic, harmless and pollution-free.
