DSM Biomedical Elasthane™ 55D Thermoplastic Polyether Polyurethane (TPU)
Categories: Polymer; Thermoplastic; Polyurethane, TP; Thermoplastic Polyurethane (TPUR), Polyether Grade

Material Notes: A high tensile strength, aromatic biomedical polymer with an exceptional combination of mechanical properties plus biological compatibility Elasthane™ TPU exhibits outstanding hydrolytic stability.

Widely Used This polyether-based polymer is designed to support long-term implantation and has been used in many commercially available medical devices including cardiovascular, neurostimulation and orthopedic implants.

Tailor Made Elasthane™ TPU can be enhanced with SME® technology to incorporate end groups that can address the needs of specific device applications. This eliminates the need for additional surface processing steps after the device component is fabricated.

Summary of Product Benefits

  • Excellent mechanical properties and abrasion resistance
  • Hydrolytically stable
  • Biocompatibile
