For us, rubber products are already a product that can be seen everywhere, and rubber products also play a powerful role in life. Early rubber is the latex obtained from rubber trees, rubber grass and other plants. High-elastic polymer compounds are divided into natural rubber and synthetic rubber, such as automobile tires, industrial products, plastic products, etc. The annual production and processing volume of rubber is particularly large. According to this trend, it is far from impossible. Meet the current production requirements. Such is the case with rubber seals, which are a type of universal basic part in sealing devices and play a very important role in the contradiction between leakage and sealing.

   With the advancement of technology in the process of human conquest of nature, the application of this product has become more and more extensive. With the advancement of society and the emergence of new sealing production equipment and technologies, the technical requirements for sealing products are becoming more and more demanding, thereby further promoting the research and development of new products. The advantage of using natural rubber is because of its good physical properties. At room temperature, it has high elasticity, slightly plasticity, very good mechanical strength, small hysteresis loss, and low heat generation during multiple deformations. Therefore, It also has good flex resistance, and because it is a non-polar rubber, it has good electrical insulating properties. Rubber, together with plastic and fiber, is known as the three major synthetic materials, and is the only polymer material with high stretchability and excellent elasticity. The biggest characteristic of rubber is firstly that the elastic modulus is very small, and the elongation is very high. The second is that it has quite good air permeability and resistance to various chemical media and electrical insulation. Some special synthetic rubbers have good oil resistance and temperature resistance, and can resist the swelling of fatty oil, lubricating oil, hydraulic oil, fuel oil and solvent oil. Cold resistance is also strong, with comprehensive performance.
