Description

General description

RESOMER^® polymers are bioresorbable aliphatic polyesters comprised of a range of different ratios of lactide and glycolide monomers, PLA stereochemistries, and end-group functionalization. These biodegradeable homopolymers and copolymers of lactide and glycolide afford a variety of properties that range from very stiff, hard semi-crystalline materials with long degradation times, to softer, amorphous materials with faster degradation rates.

Application

Controlled release

Electrospun Resomer^® X 206 S blended with cellulose from bagasse can be used as a scaffold in tissue engineering.

Features and Benefits

Controlled release of bioactive agents, sutures and bioabsorbable implantable devices.
