NA-62A is a high-performance nucleating agent for polypropylene. Its outstanding features are that it imparts good transparency, rigidity, surface gloss and heat distortion resistance to polypropylene resin, and can accelerate the crystallization rate and shorten the molding cycle of products. Compared with traditional DBS-type nucleating and transparentizing agents, it has a superior transparency enhancement effect at low concentrations, is resistant to extraction, and has no odor. It is particularly suitable for the transparency enhancement, rigidity enhancement and gloss enhancement modification of polypropylene.
