• Product description :

  This product is a non-polluting hindered phenolic antioxidant with good compatibility with polymer and high thermal oxygen resistance. It is suitable for high impact polystyrene, ABS resin, AS resin, MBS resin, polyvinyl chloride, polyacetal, polyamide, polyurethane, hydroxylated styrene-butadiene rubber and styrene-butadiene latex. The best dosage is 0.03% ~ 1%. It has remarkable synergistic effect when used with thioether antioxidant or phosphorus-containing antioxidant. This product can also be used with various types of light stabilizers to give products excellent weather resistance. In addition, this product has no effect on the polymerization reaction. For high impact polystyrene and PVC, it can be added into the monomer before polymerization.
