Most of today's rubber shock-absorbing pads are resistant to oil, acid and alkali, cold and heat, and aging. Rubber shock-absorbing pads are mostly used in military, aviation, industry, construction and other industries. According to the application characteristics, they are suitable for equipment shock absorption, etc. In the industrial industry Medium rubber shock-absorbing pads are mainly used for impact protection and shock resistance and noise reduction. Rubber shock-absorbing pads are generally used in large amounts, so when choosing them, you must pay attention to whether the quality standards are up to standard, otherwise it is easy to cause damage.

Rubber is characterized by both high elasticity and high viscosity. The elasticity of rubber is caused by the change in the conformation of its curled molecules. The interaction between rubber molecules hinders the movement of molecular chains and exhibits viscous characteristics, causing stress and strain to often be in an unbalanced state. The curly long-chain molecular structure of rubber and the weak secondary forces between molecules make the rubber material exhibit a unique viscoelastic function, so it has excellent shock absorption, sound insulation and buffering functions. Rubber parts are widely used to isolate vibrations and absorb shocks because of their hysteresis, damping, and ability to undergo reversible large deformations.

The loss factor at normal temperature is small, and the loss factor of chloroprene rubber (CR), ethylene propylene rubber (EPR), polyurethane rubber (PU) and silicone rubber is large. Rubber materials used for shock absorption purposes are generally divided into five types, namely NR, which is an ordinary rubber material; used for oil-resistant vulcanized rubber; CR used for weather-resistant vulcanized rubber; IIR used for high-damping vulcanized rubber; EPR used for heat-resistant vulcanized rubber . Although the loss factor of NR is small, its comprehensive function is good.

It has excellent elasticity, good fatigue resistance, low heat generation, small creep, good bonding function with metal parts, good cold resistance, electrical insulation and processing functions. Therefore, NR is widely used for shock absorption purposes, requiring resistance to For low temperature or weather resistance functions, CR can be used together or blended for modification. Shock absorbers made of metal salts of organic acids containing -OH groups with more than 4 carbon atoms have good durability. The compression deformation under the conditions of 70℃×22h and 40℃×148h is 17.0% and 17.0% respectively. 11.7%.
