Rubber Sealing Profile Sealing rubber and rubber-based sealing of natural rubber and synthetic rubber as the main raw material, mixed with various additives and fillers, the mastication, mixing, forming limit its kind standard than the more, a bridge type, mountain-type, P, U-shaped, Z-type, B, T, H-type, E-type, Q type. Based on the use of the case can be classified as buried rubber water stop and backing with rubber water stop. The sealing materials having excellent elasticity, abrasion resistance, aging resistance and tear function, diet modification to a strong, waterproof function is good, the temperature operating range of -45 ℃ -. + 60 ℃ when the temperature exceed 70 ℃, and When the rubber water stop by the intense oxidation effect or by the oil and other organic solvents, corrosion, shall not use rubber water stop. Often through the use of the basement wall and after pouring belt construction. Rubber Sealing classified by model can be divided into: CB Rubber Sealing (submerged center hole); CP Rubber Sealing (no pass submerged Center); EB rubber water stop ( posted outside the center hole); EP rubber water stop (posted outside the center without pass). Press materials can be divided into: natural rubber water stop, chloroprene rubber water stop, EPDM rubber water stop. By using the case can be divided into: Buried in rubber water stop and backing with rubber water stop (externally bonded rubber water-stop), steel side rubber water-stop, water swelling rubber water stop, Flatbed water stop. Currently, rubber occupation face five questions that need lower growth of traditional commodities, overcapacity and repeated construction homogenization contradiction, elements seeking to weaken the growing power standing strong differences can not, raw materials supply and shopping malls two blocked, capital environment Bound further enhanced. In inductive effect of these questions, this year, the economy of the entire operation target tire career declined, sales income, output, exports all decreased, inventories rose 2.5% as long as the occupation rate of profit. "These five questions, in the final analysis is the lack of innovation driving force becomes 'production' to 'Chi-made' is the hope for the rubber industry to carry out high-end." Deng Yali, president of Rubber Industry Association show.
