Material Notes:
PurSil® thermoplastic siliconepolyether-urethane (TSPU) is a novel copolymer that is strong, yet flexible with proven biocompatibility and biostability. Leveraging the benefits of both silicone elastomers and polyether urethanes, PurSil® TSPU has improved in vitro and in vivo stability. It has been used in medical device applications, including spinal implants and cardiac rhythm management. This polymer is backed by an established FDA Master File.Comparable strength to traditional polyether urethanes (PEU) and added biostability from the silicone co-soft segment and silicone end groups. Adaptable to various fabrication techniques to accommodate many different device shapes. Capable of being extruded and injection or compression molded, as well as solvent bonded, dipped, coated and sprayed. Available in aromatic and aliphatic versionsNon-cytoxic, Non-hemolytic, Non-genotoxic, nonmutagenic, non-pyrogenic
