With the increasing demand for environmental protection, automotive diversification, rubber recycling, and material heat resistance, the further reduction of costs has become the main direction for the development of automotive rubber products.
Sealed products account for 25%-28% of the weight of automotive rubber parts ( except tires ) . Recently, EPDM rubber with ozone resistance and weathering resistance has been widely used in automobile door and window sealing strips and gradually replaces traditional NR and CR glues. Each vehicle can use 10-15 meters long various sealing strips. In order to further reduce the cost and appearance, foreign manufacturers have used TPE materials to manufacture automotive door and window seals.
Rubber seals are a kind of universal basic components in sealing devices. They play a very important role in the contradiction between leakage and sealing. They solve the problems of leakage and sealing in the process of human conquering nature. Has been promoting technological progress, is an important way to prevent and reduce environmental pollution.
Rubber seals (Rubber seals) are a class of common base element sealing device, the seal leakage and play the role of important contradiction. Resolve leaks and seals as humans conquer nature. It has been an important way to promote technological progress and prevent and reduce environmental pollution. Rubber seals are a class of rubber products widely used in sealing technology. Because rubber has a valuable elastic polymer material and a wide temperature range, giving a smaller stress in different media will produce a larger deformation, this deformation can provide contact pressure, compensation for leakage gap, to achieve the purpose of sealing . The main products currently include rubber seals, rubber gaskets, flange gaskets, rubber damping blocks, rubber O -rings, V -rings, X -rings, Y -rings, and other forms, sizes, colors, hardness, and Rubber products of materials, although our rubber seal products started relatively slowly, but with the social progress, the emergence of new sealed production equipment and technology, the technical requirements for sealing products are more and more demanding, thus further promote the development of new products and Development.
Of the rubber seals the chamber is closed fluid overflow slit, and to prevent dust, sand and other contaminants into the interior case chamber, but if used improperly installed, or is likely to cause oil leakage, affecting the normal operation of the machine, 75- A Burns the bearing, breaks the gear, twists off the shaft, or other serious problems.
As an emerging industry that is rapidly emerging in China, environmental protection machinery will open up a new market for the hydraulic and pneumatic seal industry. Automotive, oil industry, oil and rubber components other requirements, the need to have good heat resistance, high-temperature, high-pressure, oxygen-resistant characteristics.
