Silicone rubber foam is widely used. Because of its excellent properties of silicone rubber and foam material, it has the properties of high resilience, aging resistance, and sound absorption, shock absorption and other foam properties. It is mainly used for waterproof, shock absorption, sealing gaskets (sealing grade IP68), sound insulation, insulation, Aviation insulation and other properties. Find a higher case. According to the bubble structure, silicone rubber foam is divided into three types: closed, open and mixed.

Closed cell foaming silicone foam materials have better shockproof cushioning, sound insulation, heat insulation and flame retardant and explosion-proof properties. They are mainly used in automotive field for insulation foam tube for automotive air conditioning, automotive shock absorption, foaming silicone seal gaskets for new energy vehicle batteries, etc.

At present, most automotive interior materials, such as flooring, ceiling, steering wheel, car seat and so on, are polyurethane foam materials. This is because the technology of polyurethane foam is relatively mature, and its performance meets the needs of use. On the other hand, the price of polyurethane foam is low. However, polyurethane foam has poor weatherability and flammability and releases a lot of toxic gases harmful to human body during combustion. Therefore, with the popularization of foamed silica gel materials and the improvement of people's understanding of them, the future foamed silica gel materials are expected to replace traditional polyurethane foaming materials.
