Introduction

Alithane™ ALP-B40 is medical grade aliphatic polyether-based thermoplastic polyurethanes (TPU) loaded with 40% Barium Sulfate as radiopacifier. Due to the chemical structure, aliphatic-type TPU is more light- stable and bio-stable than aromatic-type TPU. It exhibits excellent radiopacity and can be color-matched while retaining the biocompatibility, hydrolytic resistance, good mechanical properties and chemical resistance of clear grade ALP. It can be injection molded and extruded.

Biocompatibility

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