強化剤とは、材料の靭性を高めることができる添加剤を指します。. It is mainly used to improve the impact resistance, toughness and crack resistance of plastics, ゴム, coatings and other materials, so as to improve the mechanical properties and service life of materials. Toughening agents are usually polymer compounds or inorganic substances, with high molecular weight and molecular weight distribution, can form uniformly dispersed phase in the material, so as to effectively absorb and disperse stress, improve the toughness and impact resistance of the material. Common toughening agents include polyurethane, acrylate copolymer, ethylene-propylene copolymer, calcium silicate, sodium aluminum silicate, 等.
