The difference of Silicone foam sealing strip and EPDM foam sealing strip:
silicone can tolerate temperature above 200 degrees, and EPDM can tolerate much lower temperature of 200 degrees.
Foam sealing strip is a kind of sealing strip which uses the characteristics of some materials to make the pores appear inside. Divided into EPDM foam sealing strip, silicone foam sealing strip, PU foam sealing strip. The foaming sealing strip is formed by microwave vulcanization at one time. The surface is smooth and beautiful without any trace. With good elasticity and compressive deformation resistance, excellent aging resistance. Excellent flame retardancy, low smoke and low toxicity, stable product performance and high dimensional accuracy.
Foam silicone seals - product features
1.light, strong, toughness, light and strong toughness
2.heat insulation, low thermal conductivity, excellent insulation
3.non water absorption has independent bubble structure, water absorption is very low
4.excellent cushioning and impact resistance, can be used as cushioning material
5.weather resistance, weather resistance is excellent. EPDM sponge can be tested by ozone resistance (50pphm*40. C*72 hours)
