Furthermore ys 622 is effective as antioxidant and contributes significantly to the long term heat stability of polyolefins and tackifier resins. Application : Ys 622 areas of application include polyolefins(pp , pe) , olefin copolymers such as eva as well as blends of polypropylene with elastomers. In addition ys 622 is highly effective in polyacetals , polyamides and polyurethane applications. The effectiveness of ys 622 surpasses significantly that of uv absorbers , particularly in pigmented systems. Handling and safety : In accordance with good industrial practice , handle care and prevent contamination of the environment. Avoid dust formation and ignition sources .For more detailed information please refer to the material safety data sheet. 25kg/carton, 500kg/pallet
