What are the materials of the sealing strip?
There are three yuan propylene (foam, closet), Ding, rubber, silicone, neoprene, polyurethane rubber, thermoplastic vulcanizate, plasticized PVC and so on, specifically to see which kind of more suitable for all of their own
Neoprene sealantCompared with other special rubber x05, individual performance is poor, but the performance of the overall balance of good. Have excellent weather resistance, ozone resistance, aging resistance and oil resistance, solvent resistance, chemical resistance and excellent flame resistance good, has good adhesion. Poor storage stability occurs hardening phenomenon storage process, cold resistance is not good. The relative density is generally black.x05 products.Used in oil, heat, resistance to the environment. The use of temperature range -30 ~ +120 degrees. Acid-base toNBR sealing stripx05 is the main characteristics of oil resistance, solvent resistance, but not resistant to ketones, esters and chlorinated hydrocarbons such as medium, elastic and mechanical properties are good. The disadvantage is easy to crack in the ozone oxidation and aging, cold resistance, low temperature resistance.x05 using the temperature range of -30 to +120 DEG C
Three yuan EPDM sealantx05 has excellent comprehensive performance, ozone resistance, weather resistance, high temperature resistance, low temperature resistance, chemical resistance, resistance to various polar solutes, relatively low density. The disadvantage is that in general mineral oil and lubricating oil in the expansion volume, generally dark products.x05 using temperature range of -60 to + 150 degrees can be used. In high temperature, cold, strong ultraviolet radiation, the coastal areas and in high-rise buildings. With its wide application range, excellent comprehensive performance, obtained the domestic and foreign doors and windows industry recognition.Silicone rubber sealing strip
