Characteristics

Rubber seals are a common type of basic component in sealing devices and play a very important role in the contradiction between leakage and sealing. Rubber seals are a class of rubber products that are widely used in sealing technology. Because rubber has a valuable elastic polymer material, a wide temperature range, giving less stress in different media will produce large deformation, which can provide contact pressure, compensate for leakage gap, and achieve the purpose of sealing. . The main products currently have rubber seals, rubber gaskets, flange gaskets, rubber shock absorbers, rubber O-rings, V-rings, X-rings, Y-rings, and other forms, sizes, colors, hardness and The material is made of rubber.

Purpose

The rubber seal is the only polymer material with high flexibility and excellent elasticity. The biggest characteristic of rubber is firstly that the modulus of elasticity is very small and the elongation is high. Secondly, it has very good resistance to gas permeability and resistance to various chemical media and electrical insulation. Some special synthetic rubbers have good oil resistance and temperature resistance, and can resist swelling of fatty oils, lubricating oils, hydraulic oils, fuel oils and solvent oils; cold resistance can be as low as -60 ° C to -80 ° C, heat resistance can be Up to +180 ° C to +350 ° C. The rubber is also resistant to various flexing and bending deformations because the hysteresis loss is small. The third characteristic of rubber is that it can be used in combination with a plurality of materials, blended, and composited, thereby being modified to obtain good overall properties.
