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
