Sponge foam sealing strips are usually divided into two types: EPDM rubber foam sealing strips and silicone rubber low temperature resistant foam rubber sealing strips. The price difference between the two types of foam seals is also large. There are some differences between the two types of foam seals, in black, low temperature and resistance120 ℃ aging is better than EPDM foam sealing strip. The advantages of tear resistance and corrosion resistance Many customers choose this rubber foam sealing strip, especially the price is relatively suitable. The other is sponge foam sealing strip, which has the advantage of strong low temperature resistance and can reach the low temperature requirement of 280 degrees. The common colors of silicone rubber are red and red.

Features of sponge foam sealing strip:

1. Silicone resin material has good sealing performance, high temperature and weather resistance, anti-aging and impact resistance, shockproof and waterproof, and can be suitable for various smooth surface materials

2. Self-adhesive backing tape has better sealing performance, and the high temperature resistant adhesive will not fall off after long-term use. Environmental protection, safety, good insulation, high temperature resistance, small compression deformation, strong toughness

3. The foam silicone rubber foam is uniform, the density is 0.25-0.85g/cm3, and the Shore hardness is 8-30A. It is environmentally friendly, has no smell, good elasticity, good flexibility, and has no bubbles or pores on the surface. High strength, long service life, product insulation, environmental protection, high and low temperature resistance, compression resistance, acid and alkali resistance, anti-aging, anti-ultraviolet.

4. Smooth surface, uniform foam density

5. Good surface is not sticky. Good breathability

6, raw materials using silica gel, after strict testing, in line with environmental standards.

7. High temperature resistance:-70 ℃-300 ℃

8. Heat resistance: The heat resistance of silicone rubber is much better than that of ordinary rubber. It can be used almost at 150°C without any performance change; it can be used continuously for 10000 hours at 200°C; it can also be used at 350°C for a period of time.

9. Weather resistance: ordinary rubber is rapidly degraded under the action of ozone generated by corona discharge, while silicone rubber is not affected by ozone. In addition, long-term under ultraviolet and other climatic conditions, its physical properties only slightly change.

10. Anti-aging, corrosion resistance, silica gel has a strong inert

Sponge foam sealing strip is a sponge sealing product. Low density, good sealing performance, cushioning performance and elasticity. The sheet is prepared by mechanical foaming, slow gelling and injection molding of latex and then cut into strips; or continuous extrusion vulcanization of foamed rubber. Mainly used for sealing doors and windows. Sponge foam sealing strip high fire resistance. Sponge foam sealing strip is an inorganic material, which belongs to Class A fireproof material. It has good fire resistance and fully meets the fire resistance requirements of exterior wall insulation boards.2. High insulation. The high closed porosity reduces the heat transfer caused by the gas flow, which is a prerequisite for high thermal insulation.
