A nonabsorbable, braided, sterile, surgical suture composed of poly . It is prepared from fibers of high molecular weight, long-chain, linear polyesters having recurrent aromatic rings as an integral component. It's uniformly coated with polybutilate or poly. The highly adherent coating is a relatively nonreactive nonabsorbable compound which acts as a lubricant to mechanically improve the physical properties of the uncoated suture by improving handling qualities as contrasted to the braided, uncoated fiber. They are braided for optimal handling properties, and for good visibility in the surgical field and are died green.
