BEZWADA BIOMEDICAL LLC Poly (caprolactone-co-glycolide) caprolactone:glycolide 85:15, viscosity 0.50 to 1.0 dl/g, 5.0 GM
The presence of caprolactone repeat units helps in reducing the hardness and toughness of pure polyglycolide polymer and helps in decreasing the hydrolytic degradation rates of polyglycolide homopolymer due to the presence of extended alkyl chain/hydrophobicity of caprolactone.The polymers are used in medical device, drug delivery and 3D printing.
BEZWADA BIOMEDICAL LLC Poly(L-lactide-co-D,L-Lactide), L-lactide:D,L-lactide 70:30, viscosity 1.0 to 2.0 dl/g, 5.0 GM
PLA has a significantly higher crystallinity and degradation time than poly(D,L-lactide). This is attributed to the presence of all of the methyl units arranged on one side of the polymer chain sequence which results in dense packaging. Hence the presence of D,L-PLA repeat units in the L-PLA homopolymer repeat units reduces the crystallinity and enables faster hydrolytic degradation rate of L-PLA. The polymers are used in medical device, drug delivery and 3D printing.
