1. impurities are in accordance to the requirements of European Union
2. it meet the standard of environment-protecting.
Environment-protecting antimony trioxide main applied in the engineering plastic, electric wire, electric cable, the shell of household electric appliances, to equipe with the materials of anti-flaming in textile fabric to form a complete set for products of European exports. The products totally with the requirement of European Union in impurities contains, such as contains of lead, arsenic. The finished products passed the check of SGS and UL, and conformed require of environment.
