Usage
It is a kind of auxiliary antioxidant with water resistance, high volatility, and low thermal stability, which can effectively decompose hydroperoxide produced during the thermal processing of polymer materials. The product is generally not used alone, often combined with 1010/1076 and other phenolic antioxidants to improve the stability of the thermal processing of polymer materials. There are more than ten kinds of preparations of this product and phenolic antioxidants, which are widely used in polyolefin (such as polyethylene, polypropylene), polyamide, polycarbonate, ABS resin and other polymer materials. This product is only used for general chemical products, not used as food additives.
