Glass curtain wall sealing strip is to use epdm sealing strip, good elasticity, good sealing, good corrosion resistance, aging resistance, products in the three years of sun exposure without fractures) epdm seals have excellent weather resistance, ozone resistance, heat resistance, acid and alkali resistance, resistance to water vapor, color stability, electrical performance, oily and normal temperature liquid filling. Epdm rubber products can be used for a long time at 120℃ and for short or intermittent use at 150-200℃. Adding suitable anti - aging agent can increase the use temperature. Ethylene - propylene rubber with peroxide crosslinking can be used in harsh conditions. Epdm rubber seal can reach above 150h without cracking under the condition of ozone concentration of 50pphm and stretching by 30%. , weather resistance (operating temperature range -40℃-150℃), chemical resistance. After adding flame retardant has a very good fire retardant, products using microwave continuous curing technology one-time processing molding, smooth and beautiful surface, performance is more stable and not easy to change.
