NAB-82 carboxylic acid metal salt β nucleator is a new compound, has obtained many invention patents at home and abroad, and has obtained new chemical registration. This nucleator can effectively induce the formation of β-crystal PP, and the content of β-crystal is more than 87 %. The impact strength of modified PP can be increased by 2-4 times, and the thermal deformation temperature can also be greatly improved. The chemical structure is stable, well dispersed, colorless, and can improve the processing property of products. The processing window is wide, and the requirements for processing temperature and pressure are loose. At present, it has been widely used in PPR pipes, PPH plates, large injection products and lithium battery separators.
