Zinc Carboxylate Acid Scavengers for PolyEthylene and PolyPropylene  

Experience enhanced durability in your polymer systems with our VALISORB zinc carboxylates, essential acid scavengers. They neutralize acidic impurities during polymerization, preventing unwanted reactions and product degradation.  

Acids can originate from raw materials like pigments, flame retardants, or fillers, or arise during the manufacturing process in the form of catalyst residues. Since acid impurities can enter polymers in various ways, incorporating an acid scavenger is vital for preserving the final properties.
