Overview of Rubber Shock Pad 1

The most important feature of rubber anti-vibration pad is that it is made of butyl rubber. The molecular structure is mainly a cis structure, so it has excellent elasticity, crack resistance and dynamic performance. But the airtightness of butyl rubber is the best among all rubbers, and it is also its biggest advantage. Therefore, it is mainly used in tire inner tubes. Although it also has a shock absorption effect, the dynamic deflection is not ideal. The rubber shockproof pad has good resilience. Although it is lower than natural rubber, butadiene rubber and isoprene rubber, its aging resistance, corrosion resistance, chemical resistance, and high-pressure steam resistance are dominant, so EPDM is better for a comprehensive comparison. In the past, shock-absorbing rubber has been based on NR as the sole compound. In recent years, IIR, EPDM, NBR, and CR have also begun to be used to meet the ever-increasing automotive heat and oil resistance requirements, and even microporous PU elastomers and TPE thermoplastic elastomers have appeared. In addition, in accordance with the requirements of automobiles, in order to achieve the goal of lightweight, plastics instead of metals have been used to manufacture so-called rubber-plastic shock-absorbing rubber products. The Shore Hardness of ethylene-propylene rubber vulcanizates can be approximately between 25-95A. Industrial grade rubber suppliers share with you.

Principle of the rubber shock pad
The characteristics of anti-vibration pads are both high elasticity and high viscosity. The elasticity of rubber is produced by the change of its molecular conformation. The intermolecular interaction of rubber will hinder the movement of molecular chains. Stress and strain are often in an unbalanced state. The curled long-chain molecular structure of the rubber and the weak secondary forces between the molecules make the rubber material exhibit unique viscoelastic properties, and thus have good shock absorption, sound insulation and cushioning properties. Rubber parts are widely used to isolate vibrations and absorb shocks because of their hysteresis, damping, and large reversible deformation characteristics. The hysteresis and internal friction characteristics of rubber are usually expressed by loss factors. The larger the loss factor, the more significant the damping and heat generation of the rubber, and the more obvious the damping effect.
