Foam silicone rubber is a kind of spongy elastomer with pores, which is formed by condensation hydroxy-terminated silicone rubber as base material, hydroxy-hydrogen-containing silicone oil as blowing agent, and vinyl platinum complex as catalyst at room temperature. Foam silicone rubber prepared with room temperature vulcanized silicone rubber has a wide temperature range than other foam elastomers, and has high thermal stability, good insulation, heat insulation and moisture resistance, excellent shock resistance, especially at high frequency shock resistance is better, it is an ideal lightweight packaging material. It can be used for various electronic components, instruments, instruments, aircraft instrument wheels, insulation sandwich filling materials, floating materials in salt spray atmosphere and sealing materials, orthopaedic surgery filling, repair and filling materials.
   introduce:
   Silicone rubber is a linear polyorganosiloxane composed of silico-oxygen bonds (SI-O) alternately composed of its main chain, organic groups (such as methyl, ethyl, vinyl, phenyl, trifluoropropyl, etc.) composed of its side groups. Since the introduction of a small amount of vinyl into the macromolecular structure of silicone rubber can greatly improve the vulcanization and processing properties of silicone rubber, most of the silicone rubber used at present contains vinyl. Methyl vinyl silicone rubber is the most common kind of silicone rubber, which is dominant in silicone rubber products at home and abroad. Due to the particularity of the structure, silicone rubber has many other materials can not have excellent properties at the same time, such as excellent high temperature and low temperature resistance, excellent oil resistance, solvent resistance, UV resistance, radiation resistance, good aging resistance, excellent electrical insulation and chemical stability and physiological inertia.
