Introduction

Durathane™ ALC-B40 series products are medical grade aliphatic polycarbonate-based thermoplastic polyurethanes (TPU) loaded with 40% Barium Sulfate as radiopacifier. They exhibit better radiopacity than ALC-B20 and can be color-matched while retaining traits of clear grade ALC including the superior biocompatibility and mechanical properties as well as excellent resistance to oxidation, chemical, and hydrolysis. Due to the chemical structure, the aliphatic nature of ALC-B40 series products makes them more light-stable and bio-stable than the aromatic TPUs. These products can be injection molded and extruded.

Biocompatibility

Durathane™ ALC-B40 pellets passed the Hemolysis test (ISO 10993-4), MEM Elution test (ISO 10993-5), Skin Irritation test (ISO 10993-10：2010 & 10993-23：2021), Dermal Sensitization test (ISO 10993-10：2010, 2021).
