Properties:

Little odor, specific gravity: 1.24--1.28. Soluble in benzene, chloroform and carbon disulphid; Insoluble in water and dilute alkali.

Application:

his antioxidant has the characteristics of nonpolluting, heatproof, which is applied by the rubber-plastic elastomer of SBS,TPR,IPS,PVE,PE,PP, and ABS etc, because of its high stability of thermaloxidant, not fading during operating and processing, special suitable for the use as non-fading stabilizer without influence to the color of products. Therefore, it is widely applied by the products in white or bright colors, another characteristics is that the antioxidant can increase the heat resistance and the resistance to oxidation and to prevent the resinification phenomena of polymer during its processing and storing, as well as to inhibit from the phenomena of gelling and viscosity-increasing, and to prevent the thermal oxidative aging and yellowing of rubber-plastic products as well.


Storage :

It should be stored in a cool well-ventilated area
