This product is one of the few kinds of antioxidant, which is non-toxic, tasteless, light colored. The anti- oxygen effect is similar America in Uniroyal. Naugard445 and the imperial palace Japan Nocrac CD. It is widely used in various kinds of elastomers. It can be used in polyethylene, polypropylene, polyvinyl chloride and other color master batch. It can also be used as antioxidant in polyurethane foam, rubber wire, cable, food package and adhesive, especially in neoprene colorful cable's jacket for its excellent resistance to heat, light, and aging. In polyether this product can be used as light-resistant and anti-aging antioxidant, also as antioxidant for lubricating oil.
It is especially effective to be used in neoprene acrylate rubber, polyether polyalcohol for its resistance to aging caused by high temperature and light. When used together with sulfur-contained antioxidant, it has operational effect.
