Use：

This auxiliary antioxidant, compounded with the main antioxidant 1010 or 1076, has a good synergistic effect, which can effectively prevent the thermal degradation of polypropylene and polyethylene in the base injection molding, giving the polymer additional long-lasting protection.

It is non-coloring, non-polluting, good volatility resistance. It is used in polyethylene, polypropylene, polystyrene, polyester and polyamide, polyolefin, styrene mono- and copolymer, elastomers, adhesives, engineering plastics (e.g., pe, pp , pvc, ps, polyamide, polycarbonate, abs) and other polymer materials.

Dosage：

The general dosage is 0.1-1%. (The specific amount to be added is determined according to the customer's application test)

Hoard：

This product should be protected from moisture and heat. It should be placed in a cool, dry and ventilated place. 

Wrap：

Kraft paper bag lined with plastic film bag (net weight 20kg/bag)
