Umicore’s VALIKAT stannous catalysts are premium-quality, stannous-based metal carboxylates designed to drive the efficient ring-opening polymerization of cyclic esters, transforming them into high-performance aliphatic polyesters. These versatile catalysts are ideal for producing widely used biopolymers, such as Polylactic acid (PLA), Polycaprolactone (PCL), and Polyglycolic acid (PGA).

Our VALIKAT Sn catalysts stand out with their high efficiency, low racemization and exceptional stability in both air and moisture. They also support the production of high molecular weight polymers, meeting the demanding requirements of biopolymer applications.

Selecting the right catalyst is critical for fine-tuning biopolymer properties, including molecular weight distribution, thermal stability and mechanical strength. Our VALIKAT Sn catalysts support both quality and performance in all applications.
