It is very simple to distinguish the difference between the silicone foam strip and the EPDM foam sealing strip, that is, the temperature resistance of the silicone foam strip is above 200 degrees, while EPDM is much lower than this temperature.
Silicone foam strip: Silicone rubber is a new type of polymer elastic material, which has excellent high temperature resistance (250-300°C) and low temperature resistance (-40-60°C), good physiological stability, and It can withstand repeated harsh and disinfection conditions, has excellent resilience and small permanent deformation (not more than 50% in 48 hours at 200°C), breakdown voltage (20-25KV/mm), ozone resistance, and UV resistance. The sealing strip made of silicone rubber is soft and elastic, non-toxic and odorless after special processing, and can withstand high temperature, high pressure and repeated cooking at 200°C. Applied to heat insulation of electrical products, internal conduits of drinking water systems, industrial refrigeration equipment, internal connections of gas appliances, sealing of machinery, lamps and other products.
The EPDM foam strip is molded at one time by microwave vulcanization process, and the surface is smooth and beautiful without seams. It has good elasticity and compression deformation resistance, and has excellent aging resistance. Excellent flame retardant performance, low smoke and low toxicity; stable product performance, high dimensional accuracy.
Its product features:
1. Lightweight and strong toughness Lightweight and strong toughness
2. Thermal insulation, low thermal conductivity, excellent thermal insulation
3. Non-water absorption has an independent cell structure, and the water absorption is very low
4. Excellent cushioning and impact resistance, can be used as cushioning material
5. Weather resistance Excellent weather resistance. EPDM sponge can pass the ozone resistance test (50pphm*40. C*72 hours)
