PDLLA Fast Crystallizing — Poly(D,L-lactic acid), Fast Crystallizing
PDLLA Fast Crystallizing is a random copolymer of D- and L-lactic acid, resulting in an amorphous polymer with a lower melting point and faster degradation rate. Its fast crystallization characteristic is beneficial for processing, especially in medical device manufacturing where precise control over degradation is crucial.
