Performance characteristics of foamed rubber seals: 1. Environmental protection and safety, good insulation, high temperature resistance, small shrinkage deformation, strong rebound resilience; 2. Flat surface, balanced foam density; 3. Acid and alkali resistance, aging resistance, non-toxic; 4. The superior upper layer is non-sticky and has good air permeability; 5. Adopt 100% high-quality silicone material and pass severe testing to meet environmental protection requirements. 6. Can be self-adhesive with backing tape, better sealing performance, high temperature resistant adhesive will never be applied. The ozone-resistant performance of black rubber foam sealing strips-EPDM rubber is known as "non-cracked rubber" and has good ozone resistance in general rubber. Good thermal consolidation. Noble aging resistance-can be applied permanently at 130 ° C, and can be applied intermittently or short-term at 150 ° C or a little higher.
