Foamed silica gel is generally used as a material for buffering, insulation and other purposes. It is usually produced by using azodicarbonamide, azobisisobutyronitrile, etc. as a foaming agent after vulcanization and foaming. The internal structure is a perforated elastic silica gel. , specifically resistant to high and low temperatures, and can be modified into flame-retardant silica gel to meet UL-94V0 standards. Products using dimethyl-2,2-azobisisobutyrate as the blowing agent can meet the requirements of environmental protection and non-toxicity because no cyanide is produced.

Foamed silicone can be formamide-free, toluene-free, non-toxic and environmentally friendly. It has excellent foaming performance, the foaming effect is 1-4 times, and the density after foaming is 0.3-0.8g/cm3; it has excellent high and low temperature resistance (can be used at -60 to +200 degrees for a long time, and can withstand low temperatures in an instant - 110 degrees; high temperature resistance 300 degrees), is not easily oxidized and degraded in ozone and radiation environments, and has good chemical stability; it also has excellent electrical insulation, hydrophobicity, moisture resistance, shock absorption, thermal insulation, and physiological inertness.
