The foam sealing strip is similar to the foam rubber sealing strip. It has the following characteristics: water resistance, closed cell layout, no water absorption, moisture-proof, waterproof; corrosion resistance, seawater, grease, acid, alkali and other chemical corrosion; antibacterial, non-toxic, tasteless and pollution-free; high resilience and tension resistance, strong resistance, excellent shock and buffer functions; excellent heat insulation, heat preservation, cold protection and low temperature function Good, resistant to extreme cold and exposure; sound insulation closed cell, good sound insulation.

The dense sealing strip has good corrosion resistance and aging resistance (the product is exposed to the sun for three years without cracks). EPDM sealing strip has excellent weather resistance, ozone resistance, heat resistance, acid and alkali resistance, water vapor resistance, color stability, electrical performance, oil filling and room temperature fluidity. EPDM products can be used for a long time at 120 ℃, and can be used briefly or intermittently at 150-200 ℃. The use temperature can be increased by adding suitable antioxidant. EPDM crosslinked with peroxide can be used under harsh conditions.

Under the condition of ozone concentration of 50 PPHM and tensile strength of 30%, EPDM rubber sealing strip can not crack for more than 150 H. Weather resistance (service temperature range – 40 ℃ – 150 ℃), chemical resistance. After adding flame retardant, it has good fire resistance and flame retardancy. The product is processed in one time by microwave continuous vulcanization process. The surface is smooth and beautiful, and the performance is more stable and not easy to change.
