Antioxidant DNP is one of the important low toxicity antioxidants for rubber and plastic processing.

Anti-aging, anti-copper, manganese and other harmful metal properties of antioxidant DNP is widely used in copper, manganese and other harmful metal inhibition and heat resistance, anti-aging, anti-aging, Aging of antioxidants on thiazole accelerator has a significant activation. Applicable to cable, rubber and other industrial rubber products and brown or dark latex products. It is a general-purpose antioxidant for natural rubber and synthetic rubber, mainly used as antioxidant in rubber, latex and plastic. Anti-aging agent DNP is both a chain-breaking inhibitor, but also a metal complexing agent, excellent heat aging, resistance to natural aging and anti-copper, manganese and other harmful metal role. In styrene-butadiene rubber in the anti-ultraviolet function.
