Blowing agent

Chemical blowing agent is an additive to plastic or rubber that evolves gas through thermal decomposition at specific temperatures and pressures for specified durations to form fine cellular foam. This uniform cell structures in a polymeric matrix brings high elasticity/ tension, thermal insulation, weight reduction, sound insulation and shock absorption to polymeric products, increasing production yield and lowering raw material usage, energy usage, and production time. Chemical blowing agent is classified into organic and inorganic chemical blowing agent and applications are outlined as follows. Automotive/ building Interiors like wallpaper, flooring, decoration materials, HVAC system Insulation, packaging materials, life jackets, and shoes etc.
