Foamed silica gel sealing strip is a kind of sealing strip that makes use of the characteristics of some materials to produce air holes in its interior through processing. It is divided into ethylene propylene diene monomer (EPDM) foam sealing strip, silica gel foam sealing strip and PU foam sealing strip. The foam sealing strip is formed by microwave vulcanization process at one time, and its surface is smooth and beautiful, without contact marks. It has good elasticity, compression deformation resistance and excellent aging resistance. Excellent flame retardancy, low smoke and low toxicity; The product has stable performance and high dimensional accuracy.

Product features:
1. Light weight, strong toughness, light weight and strong toughness
2. Thermal insulation, low thermal conductivity, superior thermal insulation
3. Non water absorption has independent bubble structure and low water absorption
4. Excellent cushioning and impact resistance, which can be used as cushioning materials
5. Excellent weather resistance. EPDM sponge can pass the ozone resistance test (50pphm * 40. C * 72h)

Product use:
1. Packaging materials (cushioning materials for transportation of precision machinery, medical appliances, furniture, glass, etc., protective cushioning materials for small electrical appliances, etc.)
2. Civil engineering and architecture (caulking materials for large plates for residential use, sealing materials for doors and windows for residential use, gasket materials for concrete anti shrinkage, caulking materials for open channels and waterways, various caulking materials for civil architecture, etc.)
3. Vehicles and ships (door sealing materials, luggage compartment sealing materials, engine hood buffer gaskets, various pipe sealing materials, lamp sealing materials, engine shockproof materials, buffering and sealing materials for instruments, etc.)
4. Heat insulation and heat preservation (heat insulation sealing materials are used for coolers and air conditioners, refrigerators and freezers, etc.)
5. Sound insulation and moisture-proof (anti noise sealing materials for various mechanical equipment, residential sound insulation wall sealing materials, waterproof and moisture-proof sealing materials for various electrical appliances, moisture-proof sealing materials for various mechanical equipment, etc.).

Silicone rubber is a new type of polymer elastic material. It has excellent high temperature resistance (250-300 ℃) and low temperature resistance (- 40-60 ℃) properties, good physiological stability, and can withstand repeated harsh and disinfection conditions. It has excellent resilience and small permanent deformation (no more than 50% at 200 ℃ for 48 hours), breakdown voltage (20-25KV/mm), ozone resistance, and ultraviolet resistance. The sealing strip made of silicone rubber is soft and elastic, non-toxic and odorless after special processing, and can withstand 200 ℃ high temperature, high pressure and repeated cooking. It is used for insulation of electrical products, internal conduit of drinking water system, internal connection of industrial refrigeration equipment and gas appliances, and sealing of machinery, lamps and other products.
