Rubber Seal Scalability And Flexibility Is Excellent

Rubber seals are a common type of basic element in seals and play a very important role in the conflict between leaks and seals. Solve leaks and sealing problems in the process of human conquest of nature. An important way to promote technological progress and prevent and reduce environmental pollution has always been. Rubber seals are a type of rubber products widely used in sealing technology. Because rubber has a valuable elasticity of the polymer material, a wide temperature range, giving less stress in different media will produce greater deformation, this deformation can provide contact pressure, compensate for the leakage gap, to achieve the purpose of sealing . The main products currently include rubber seals, rubber gaskets, flange gaskets, rubber shock absorbers, rubber O-rings, V-rings, X-rings, Y-rings and other forms, sizes, colors, The rubber products, although our rubber seal products started relatively slowly, but with the social progress, the emergence of new sealing production equipment and technology, the technical requirements of sealing products more and more harsh, so as to further promote the development of new products and Development.

Types of rubber seals

1, according to the appearance of rubber

Rubber can be divided into solid rubber (also known as dry glue), latex rubber (referred to as latex), liquid rubber and powder rubber four categories.

2, according to the source of raw materials and methods

Rubber can be divided into two categories of natural rubber and synthetic rubber. Natural rubber consumption which accounts for 1/3, synthetic rubber consumption accounted for 2/3.

3, according to the physical form of rubber

Rubber can be divided into hard rubber and soft rubber, raw rubber and rubber mixture.

4, according to the rubber properties and uses

In addition to natural rubber, synthetic rubber can be divided into general-purpose synthetic rubber, semi-synthetic rubber, synthetic rubber and specialty synthetic rubber

5, according to the rubber in industrial use

Can be divided into ordinary rubber, heat-resistant rubber, oil-resistant rubber and weather-resistant rubber, resistant to special chemical medium rubber.

Rubber seal features

1, scalability and flexibility is excellent

Rubber, with plastic, fiber and known as the three major synthetic materials, is the only highly scalable and extremely flexible polymer materials. The biggest feature of rubber is first of all its modulus of elasticity is very small, while the elongation is high.

2, breathable, excellent electrical insulation

Second is that it has a very good resistance to air permeability and resistance to various chemical media and electrical insulation properties. Some special synthetic rubber more have good oil resistance and temperature resistance, resistant to fatty oils, lubricants, hydraulic oil, fuel oil and solvent oil swelling;

3, cold, heat, good overall performance

Cold can be as low as -60 ℃ to -80 ℃, heat can be as high as + 180 ℃ to +350 ℃. Rubber also resistant to all kinds of music, bending deformation, because the hysteresis loss. The third feature of rubber is that it can be used in combination with a variety of materials, blended, composited, and thus modified to achieve good overall performance.
