PRODUCT FEATURES AND APPLICATIONS
*  AN 618 is a new type of phosphite antioxidant with excellent performance.With high phosphorus, it has strong ability to decompose hydroperoxide and excellent initial color.It can be used in food packaging materials, replacing antioxidant BHT and auxiliary antioxidant DLTDP
*  AN 618 is mainly used for polyethylene, polystyrene, polypropylene, ABS resin, EVA copolymer, polyvinyl chloride and polycarbonate.
*  AN 618 is often used together with hindered phenolic antioxidants or hindered amine light stabilizers to synergistic effects. The dosage is 0.3%-0.5%
*As thermal resistant antioxidant , AN 618 is often used in combination with hindered phenolic antioxidants, for ABS, PS, HIPS, NBR, SBS, PP, PE, LLDPE, PVC, PC, PA, PET, PU,polyamide fiber, Polyester fiber, paint, ink or compounds of metal heat stabilizer.
*Due to the diphosphite structure,it has high level trivalent phosphorus and effective anti-aging performance.
