Product Description

Uses: 
It can be used as a multifunctional synergistic additive for antimony oxide or other halogen flame retardants. It can effectively improve flame retardancy, reduce smoke generation during combustion, and adjust the chemical, mechanical, electrical and other properties of rubber and plastic products. As a partial or complete environmentally friendly substitute for halogen-containing flame retardants, it is widely used directly in the processing of plastics and rubber, such as PVC, PE, PP, reinforced polyamide, polychloride, polystyrene, epoxy resin, Polyester acid vinyl resin and natural rubber, styrene butadiene rubber, neoprene, etc. It can be used in the production of paper, fiber fabrics, decorative boards, floor leather, wallpaper, carpets, ceramic glazes, fungicides, and coatings to improve flame retardancy. It can also be used for anti-corrosion, far-infrared absorption, wood pest control and anti-bacterial treatment.
