The automobile industry seal is not so much as the latest seal material, but it is not in fact, and the silicone rubber has a history of decades in China. A few years ago, is indeed the pride, the rubber is very delicate, gradually reduce the cost in recent years, it has been gradually applied to the building on the seal. Silicone rubber than ethylene propylene rubber for sealing the advantages, is compared with the compression performance of EPDM rubber better so, better sealing performance, and from the time temperature equivalent principle, silicone rubber temperature can reach 300 DEG, 180 DEG C resistant EPDM rubber is the best, in the life of silicone rubber under the condition of the same temperature is two times of EPDM glue, longer service life.

It has excellent physiological inert, non-toxic, tasteless, silicone rubber has excellent heat resistance, cold resistance, dielectric properties and ozone resistance and ageing resistance properties, outstanding performance of silicone rubber is the use of wide temperature, at -60 DEG C (or lower temperature) to +250 DEG C (or higher the temperature under long-term use). Therefore, silicone rubber is the ideal choice for the construction seal in the present era. In a word, the era in the continuous progress, China's seal industry should make brand, bid farewell to the era of low price competition, standard management. I believe that with the development of China's sealing strips, the Chinese seal industry will flourish as the spring bamboo shoots are springing up.

The sealing strip is a product sealed by one thing, and it is not easy to open. It plays the role of shock absorption, waterproof, sound insulation, heat insulation, dustproof and fixing. The sealing strip is made of rubber, paper, metal, plastic and many kinds of materials. At present, there are five main types of sealing materials: silicone sealing strips, EPDM seals, TPV seals, TPE seals, and PVC seals. Today, it is a brief introduction to the advantages and disadvantages of these materials. EPDM sealing strip like PVC products, not by pure EPDM, it also requires the addition of reinforcing material, carbon black, rubber and clay in EPDM. Processed oil, paraffin oil, naphthenic oil and other materials, vulcanizing agents, additives and other materials, after mixing and extrusion vulcanization to get the final seal products.

The molecular structures of three EPDM rubber other special gives it than in the past is often used, such as NR SBR, natural rubber, styrene butadiene rubber, chloroprene rubber CR, more excellent resistance to sunlight, oxygen resistance, UV resistance, radiation resistance, aging resistance, and good mechanical properties, it quickly in sealing in particular, applications in automotive sealing systems in the field instead of the above materials, and is widely used.

Some companies use different quality, complex components of waste plastics to produce seals, and when blending, they do not add modifiers, and at the same time, they add too much filler, that is to say, they become high filled sealing strips. This adhesive strip has poor strength, low elasticity and easy to fracture. Some manufacturers also add alternative plasticizers or aromatic oil refining slag and other drainage oil, make the seal products not only pungent odor, and drainage oil and other substances in the short term is not compatible, automatically overflow from the finished strip, then it will lose the other material oil shrinkage hard, dry, or even fall off.

The sealing strip plays an important role in waterproof, sealing and energy saving, sound insulation, dust proof, antifreeze and warm keeping. It must have strong tensile strength, good elasticity and better temperature resistance and aging resistance. In order to ensure the fastening of the glue bar and the profile, the section size of the adhesive strip must match the profile of the door and window.
