Automotive rubber seal shock-absorbing products are often used in machinery, vehicles, aircraft, ships, bridges, railways and other fields. The role of rubber shock-absorbing pads can replace metal springs to play a role in vibration absorption. Its main performance requirements are static stiffness, dynamic stiffness and durability.

Most of the characteristics of buffer rubber products are as follows: 1. Rubber products are composed of a variety of materials. The same shape can have different properties through material adjustment; 2. The friction between the internal molecules of rubber gives it a certain damping performance; 3. Rubber will produce different elastic coefficients during compression, shearing and stretching. The damping performance of shock-absorbing rubber products mainly depends on the molecular structure of rubber, so choosing which rubber material to customize the rubber products is a key point. Rubber air springs are mainly used in automobiles, trams, and railway vehicles. It is a suspension system that fills compressed air in the capsule and uses the elasticity of air and the characteristics of rubber to obtain comprehensive buffering and vibration reduction effects. Rubber fenders are a kind of rubber products used between ships and docks and between ships when ships are docked to withstand impact loads and absorb kinetic energy.
