　　Characteristics and Uses

　　This product is suitable for polyolefin as well as its copolymer and synthetic rubber, etc. It not only can improve the polymer' s light resistance, but also can increase the dyeing behavior and the antioxygenic property. It can strengthen the weathering resistance and stainability of the polypropylene fibre, it can lengthen the polyethylene film' s useful life. It can be used in the polyethylene fish twine, for it has good spinnability, knot strength and tensile strength.

　　It is especially suitable for polypropylene, polyethylene film, braided strap and fibre products. When we use the product with the ultraviolet absorber, secondary antioxidant, etc simultaneously, they have the synergetic effect.

　　Common usage level: 0.1~ 1.0% .
