NP-828 is a sorbitol-based transparent nucleating agent, a small amount added
to polypropylene can significantly improve the transparency of the product.
NP-828 is applied to homopolymerization and random copolymerization polypropylene,
which can significantly reduce the haze of PP products, improve the transparency and
surface gloss of products, improve the rigidity and heat resistance of materials, improve
the crystallization rate and crystallization temperature of PP, shorten the molding cycle of
Produktoj, and improve production efficiency. This product is insoluble in water,
non-toxic and tasteless, excellent heat resistance, can be used in the production of household
and food contact with high-grade transparent polypropylene products.
