CAI Performance Additives ST-PA210

ST-PA210 is essential flow improver for biobased and biodegradable plastics. Recently also approved for use with polycarbonate copolymers! Utilizing low dosings, the ST-PA210 additive is uniquely suited for increasing melt flow index, compatibility & elongation, and improving dispersion in the emerging world of bioplastics. Our customers report verified performance enhancement with no waxy residues.
