Brief introduction of automobile door edge sealing strip knowledge automobile door edge sealing strip is used to maintain the sealing of movable parts such as door and window glass, front and rear windows, triangle windows, etc. the shape and section of the sealing strip should meet the requirements of different use parts and different functions. The reason why the automobile can effectively block the pollution and noise in the environment depends on the tightness and sound insulation of the whole automobile Good sex. According to the customer's request, we can produce all kinds of adhesive strips.
EPDM rubber has a similar hand feel from - 50 ℃ to 150 ℃, which invents operation results for production site installation because EPDM has outstanding ozone resistance, low-temperature elasticity of automobile door edge sealing strip, and the temperature when stretching can reach - 58.8 ℃. Because of its excellent physical and mechanical properties, it is often used to manufacture sealing parts of aircraft, buses, ships, high and low voltage switchgear, glass curtain walls, aluminum alloy heat cut-off windows, as well as diving products, high-pressure steam hoses, tunnels, viaduct joint No. waterproof parts and other industrial and agricultural sealing parts.
It has good elasticity and compression deformation resistance, will not crack or deform in long-term use, and can maintain its original high sealing performance between - 50 ° and 120 ° C. The experience in the cross-section design of rubber strip and the comprehensive design of the system ensure good waterproof, dustproof, sound insulation, temperature insulation and shock absorption. The sealing strip is easy to install, firm and reliable, and the movable door switch is light. Production technology of automobile sealing strip
The door edge sealing strip of EPDM automobile is polymerized by adding a small amount of non conjugated diene into ethylene and propylene monomers. The characteristic of its structure is that there is no unsaturated double bond in the main chain of polymer molecule, but the unsaturated double bond is introduced in the branch chain. Therefore, it has excellent weather resistance, heat resistance, ozone resistance, UV resistance, good processing performance and low compression permanent deformation, and is the preferred material for production of sealing strips.
Silica gel material has good sealing performance, high temperature resistance and weather resistance, anti-aging and impact resistance, waterproof and shockproof, and can be applied to all kinds of smooth surface materials. Silicone seal strips are used for liquid and gas seals of various large chemicals and daily necessities, which can completely isolate the relationship between the carrier and the outside world and effectively preserve objects. It is a colorless or semitransparent oily liquid. After vulcanization, it becomes a soft elastic material. It can be used to make patch, antiskid pad, high temperature mold and other flexible silicone rubber products
