polypropylene

/poly·pro·py·lene/ (pol″e-pro´pĭ-lēn) a synthetic, crystalline, thermoplastic polymer with a molecular weight of 40,000 or more and the general formula (C3H5)n; uses include nonabsorbable sutures, surgical casts, and the membranes for membrane oxygenators.

polypropylene

a polyolefin available in monofilament form and used as a nonabsorbable surgical suture. Very popular as a vascular suture material. Like most synthetics it has poor knot security but it causes little tissue reaction and has very long life. It is also available in mesh form.
