DSM Biomedical CarboSil® 20 80A Thermoplastic Silicone Polycarbonate Polyurethane (TSPCU)
Categories: Polymer; Thermoplastic; Polycarbonate (PC); Polyurethane, TP; Silicone Polyurethane, Polycarbonate Based

Material Notes: A ground-breaking copolymer that combines the biocompatibility and biostability of conventional silicone elastomers with the processability and toughness of thermoplastic polycarbonate-urethanes

The silicone portion of CarboSil® TSPCU works synergistically with the polycarbonate component to improve stability. This medical grade polymer is highly biocompatible and well suited to be used in many types of medical devices.

Flexible CarboSil® TSPCU is comparable in tensile strength to traditional polycarbonate urethanes and derives additional biostability from the silicone portion. The material is adaptable to various fabrication techniques to accommodate many different device shapes. It can be extruded, injection or compression molded, solvent bonded, dipped coated and sprayed.

Widely Used Because of its tensile strength, biocompatibility and flexibility, CarboSil® TSPCU is used in a wide range of medical applications, including cardiovascular and nervous system electrostimulation, continuous glucose monitoring, drug eluting and orthopedic implants.

Tailor Made CarboSil® TSPCU can be enhanced with SME® technology to incorporate end groups that can address the needs of specific device applications (silicone end groups are standard). This eliminates the need for additional surface processing steps after the device component is fabricated.
