Composed of polybutester, a copolymer of butylene terephthalate and poly-teramethylene ether glycol. Coated with Polytribolate, an absorbable polymer of ecaprolactone/glycolide/poloxamer 188. The unique properties of these sutures are conferred by the composition and structure of the polybutester fiber which give the suture minimal memory, less tissue dray and smooth know run-down, fray resistance and easy handing.
