Purpose

Flame retardant zinc borate is an inorganic additive flame retardant, characterized by good thermal stability, which can be both flame retardant and smoke suppressant. It can replace antimony trioxide in some products or be used in conjunction with other inorganic flame retardants, resulting in better results. This product is widely used in industries such as rubber, plastic, cables, wood, defense and military products, coatings, tarpaulins, etc. Zinc borate can serve as a multifunctional synergistic additive for antimony oxide or other halogen flame retardants, effectively improving flame retardancy, reducing smoke generation during combustion, and adjusting the physical, mechanical, and electrical properties of rubber and plastic products. Zinc borate is widely used in PVC materials, such as carpets, conveyor belts, wires and cables, as well as in engineering plastics with halogen-free aluminum hydroxide and magnesium hydroxide as flame retardant systems, such as PE, PP, ABS, etc. It is also used in expansion coatings, ceramic glazes, fungicides, wallpaper treatment, milky white glass, and other fields.
