Silicone foam material (also known as: silicone foam/foamed silicone) is made of raw silicone rubber, fillers, vulcanization accelerators, styrofoam, etc. as raw materials. After being uniformly mixed, it is subjected to a special process in high pressure A porous, low-density, compressible polymer elastomer made at high temperature. Because of the high elasticity of silicone rubber and the sound insulation and shock absorption properties of foam materials, it is widely used in life and is mostly used as vibration damping pads, sealing gaskets, sound-absorbing materials, insulating materials, and airline thermal insulation materials. According to the cell structure, silicone foam is divided into three types: closed cell, open cell and mixed type.

      The closed-cell foamed silicone foam material has good shock-proof buffering, sound insulation, thermal insulation, flame-retardant and explosion-proof characteristics. It is mainly used in the automotive field for thermal insulation foam pipes for automotive air conditioning, automotive shock absorption, and new energy. Foamed silicone gaskets for automobile batteries, etc. Nowadays, many automotive interior materials, such as floor, ceiling, steering wheel, car seat, etc., are all polyurethane foam materials. On the one hand, the technology of polyurethane foam materials is relatively mature and the performance meets the standard of use; on the other hand, it is Because the price of polyurethane foam material is lower. However, polyurethane foam materials have poor weather resistance, are flammable, and release a large amount of toxic gases harmful to the human body during combustion. Therefore, with the promotion of silicone foam materials and the improvement of people's awareness of them, the future silicone foam materials are expected to replace traditional polyurethane foam foam materials.
