Antioxidant 245 is a highly efficient asymmetric hindered phenol antioxidant, which has the outstanding characteristics of high antioxidant efficiency, low volatility, excellent resistance to oxidation and coloring, and a significant synergistic effect with auxiliary antioxidants (such as thioesters or phosphites). When used in combination with light stabilizers, it can give products excellent weather resistance.
This antioxidant has excellent compatibility with polymers and high thermal oxidation resistance. It works well with high-impact polystyrene, ABS resin, AS resin, MBS resin, polyvinyl chloride, polyoxymethylene, polyamide, polyurethane, hydroxylated styrene-butadiene rubber, and styrene-butadiene latex. In the field of polyurethane materials, it can be used in RIM, TPU, spandex, polyurethane adhesives, sealants, and other products. It can be used in combination with auxiliary stabilizers, such as thioesters, phosphites, phosphonites, and lactones, as well as light stabilizers and their functional stabilizers.
