What are the raw materials for the production of rear shock absorber bumper block?

- Apr 25, 2019-

The rear shock absorber bumper block is a device capable of limiting the maximum deformation of the suspension. It reduces the direct impact of the axle on the frame and prevents excessive deformation of the elastic member. The rear shock absorber bumper block is composed of rubber blocks, steel plates and bolts, and some buffer blocks are made of porous polyurethane and have a hollow interior.


Most of the rear bumper bumper blocks of automobiles are made of porous polyurethane material, and rubber materials are gradually being replaced. The porous buffer block made of polyurethane material has the advantages that the following rubber cannot replace, for example, the small mass is about 1/2 deformation of the rubber buffer block of the same size, and has good nonlinear characteristics.


The rear shock absorber bumper block uses natural rubber and other composite rubber as the main raw material buffer block, and adds special reinforcing agent, which has smooth buffer block picture, anti-bending, anti-stretching and high air tightness. Its reinforcing layer is made of high-quality and high-strength cord as the main material, and the surface layer is attached with high-strength rubber. It has the characteristics of high pressure resistance, ultra-lightweight, high softness and high temperature resistance. High-strength rubber is attached to the process to ensure that delamination and faults do not occur during operation. External rubber: It is made of imported natural rubber, styrene-butadiene rubber and other raw materials. It has light and anti-aging properties.
