DSM Biomedical PurSil® 20 Thermoplastic Silicone Polyether Polyurethane (TSPU)
Categories: Polymer; Thermoplastic; Polyurethane, TP; Silicone Polyurethane, Ether Based

Material Notes: A novel copolymer that is strong yet flexible with proven biocompatibility and biostability Combining the benefits of both silicone elastomers and polyether urethanes, PurSil® TSPU has exceptional stability.

Flexible PurSil® TSPU is comparable in tensile strength to traditional polyether urethanes with added biostability from the silicone component. It is adaptable to various fabrication techniques to accommodate many different device shapes and can be extruded, injection or compression molded, solvent bonded, dipped coated and sprayed. This highly flexible polymer is available in aromatic and aliphatic versions.

Widely Used Because of its outstanding flexibility, oxidative stability and thromboresistance, PurSil® TSPU is used in a wide range of medical devices, including ophthalmic, anastomotic, and continuous glucose monitoring.

Tailor Made PurSil® TSPU can be enhanced with SME® technology to incorporate end groups such as fluorocarbon and/or polyethylene oxide (silicone end groups are standard). This eliminates the need for additional surface processing steps after the device component is fabricated.

Summary of Product Benefits

  • Biostable and biocompatible
  • Adaptable to many different processing techniques
  • Excellent mechanical properties relative to conventional silicone elastomers
  • Thromboresistant
  • Enhanced with SME® technology utilizing various surface modifying end groups
  • Comprehensive FDA Master File
