Rubber products for us, is already everywhere products, rubber products also play a powerful role in life. Early rubber is taken from rubber trees, rubber grass and other plants latex, after processing made of elastic, insulating, impervious to water and air materials. High elastic polymer compounds are divided into natural rubber and synthetic rubber, such as auto tires, industrial products, plastic products, etc., the annual production and processing of rubber is particularly large, according to this trend, far from meeting the current production requirements. Rubber seals are such, it is a kind of general basic parts in the sealing device, and plays a very important role in the contradiction between leakage and sealing.

With the process of human conquest of nature, the advancement of technology has made the application of this product more and more extensive. The society is progressing, the emergence of new sealing production equipment and technology, and the technical requirements for sealing products are becoming more and more demanding, thus further promoting the research and development of new products. The advantage of natural rubber is that it has good physical properties, at room temperature, high elasticity, slightly plastic, very good mechanical strength, low hysteresis loss, low heat generation during multiple deformation, so its flexural resistance is also very good, and because it is non-polar rubber, it has good electrical insulation properties. Rubber, known as the three major synthetic materials with plastics and fibers, is the only polymer material with high scalability and excellent elasticity. The biggest feature of rubber is first that the elastic modulus is very small, and the elongation is very high. Secondly, it has quite good resistance to air permeability and resistance to various chemical media and electrical insulation properties. Some special synthetic rubber has better oil resistance and temperature resistance, can resist the swelling of fat oil, lubricating oil, hydraulic oil, fuel oil and solvent oil. Cold resistance is also strong, with comprehensive performance.
