Industry knowledge:
Zinc acetylacetonate (ZAA) is a stabilized zinc-based additive that can be used in plastics such as polyvinyl chloride, polystyrene and polyolefin resins to help increase their durability, toughness and heat resistance; this allows for greater flexibility and a lighter product.
Zinc acetylacetonate (ZAA) is a yellow crystalline powder and is an excellent addition to PVC resin systems. It enhances the mechanical properties, toughness and thermal/light stability of PVC compounds. This product can be used to stabilise PVC at lower temperature than conventional zinc additives.This stabilizer is good to improve the mechanical property and processability of PVC resin, especially for heat-shaped products.
