Divided into EPDM foam seals, silicone foam seals, PU foam seals. The foamed sealing strip is formed by microwave vulcanization process, and the surface is smooth and beautiful without contact. Has good elasticity and resistance to compression deformation, excellent aging resistance. Excellent flame retardancy, low smoke and low toxicity; stable product performance and high dimensional accuracy. At the same time, place the PVC sealing strip and silicone rubber sealing strip at a high temperature for a period of time (placed on the roof or in a sunny place). The PVC sealing strip will become very soft for a short time. And yellow (oil is easy to absorb soil) seep oil, stain your hands, dirty hands; the physical properties of silicone rubber seals have not changed, the pressure cooker seals for domestic use are silicone rubber, which uses the high temperature resistance and non-toxicity of silicone rubber Environmental protection performance. There is no obvious change in physical properties of silicone rubber under ℃ working environment.
