Composite sealant strip is a product with a composite structure, usually composed of two or more different materials, with excellent sealing performance and dustproof, waterproof, sound insulation, shock absorption and other properties. This type of adhesive strip is commonly used in the sealing and protection of automotive doors, windows, curtain walls, and other construction fields.

Rubber sealing strip is a strip rubber sealing product. A rubber sealing element applied to railway locomotives, automobiles, airplanes, high-rise buildings, refrigerators, and various industrial components to prevent external dust, air, water, etc. from entering the system. The product is non-toxic and environmentally friendly. It has excellent anti-aging, high and low temperature resistance and corrosion resistance. It has good elasticity and compression deformation resistance. It will not crack or deform after long-term use. Its original high sealing performance can be maintained between -50 ° C and 120 ° C.

1. High temperature resistance. Silicone sealing strips can maintain good elasticity at high temperatures, with a common high temperature resistance range of 200~280 ℃, and can even withstand temperatures as high as 350 ℃ in some cases. 2. Low temperature resistance. Compared with ordinary rubber, silicone has better low-temperature performance and can maintain elasticity at extremely low temperatures. Some special formulations of silicone can even withstand lower temperatures. 3. Weather resistance. Silicone sealing strips have good ozone and UV resistance, making them suitable for use in harsh environments. 4. Insulation. Silicone has a high electrical resistivity and can maintain stable insulation performance over a wide temperature and frequency range. 5. Flame retardancy. Silicone itself is flammable, but after adding flame retardants, it has flame retardancy and self extinguishing properties, and does not produce a large amount of smoke or toxic gases during combustion. 6. Non toxic and odorless. Silicone sealing strips are generally considered non-toxic and suitable for applications in contact with food. 7. Anti aging. Silicone sealing strips are not prone to aging and have a long service life. 8. Good rebound performance. Even at high temperatures, the deformation of the silicone sealing strip is relatively small.
