    Applications
    Non-polluting thermal-oxidation resisting antioxidant . suitable for SBS, TPR, TPS, PS, SBR, BR, PVC, PE, PP, ABS and other rubber elastomers, with high thermal oxidative stability performance, processing, does not change colors in process, especially suitable for non-color-change stabilizer. No bad effects on product color; widely used in white and chromic products. Can improve the heat resistance of rubber and plastic products, and oxidation resistance; can prevent the polymer from resin phenomenon in the manufacture and storage. It can inhibit gel formation and Viscosity increase, to prevent thermal aging and yellowing of rubber and plastic products

    Packing and Storage
    Package: 200kg/metal pail
    Storage: Store in closed containers in a cool, dry, well-ventilated place. Avoid exposure under direct sunlight.
