Product application
This product serves as a halogen absorber in polyolefins to reduce product corrosion on processing equipment. Meanwhile, it can eliminate the negative effects of residual catalyst in the resin on the color and stability of the resin. It may be extensively utilized to enhance the heat resistance of plastics, increase the initial coloring and air permeability of weather resistance, and substitute hazardous stabilizers while maintaining the same performance.
Product packaging
This product is packed in kraft paper bags with Neimura plastic film, 20kg/bag. It can be packaged according to client requirements.
