Application
NAP-4 is widely used in Homo PP, Random CO-PP, and also high molecular weight PE products. Besides improving the balance of gloss, rigidity and HDT performances, it shortens the molding cycle time as well.
Usage
NAP-4 can be fed directly into injection or extrusion; or be supplied by master batches.
Recommended dosage is 0.2～0.3%.
Packaging and Storage
Packed in carton with inner PE bag, 15Kg net each.
Store in cool, dry and ventilated place. Avoid direct exposure to the sun as well as heat source and humidity.
