Azodicarbonamide has high gas generation and excellent dispersion characteristics in rubber and plastics, and both atmospheric pressure foaming and pressure foaming are applicable. It is widely used in the foaming of plastic rubber, such as PE, PS, EVA, PVC, TPR, natural rubber and other materials. It can also be used to make foaming materials such as sport equipment, leather, wallpaper, floor, yoga mat, and shoe soles. It is especially beneficial to increase the elongation of the product and to obtain a better cell structure result.
