ALITHANE™ ALP-90A-B20
TPU(热塑性聚氨酯)
H泓格生医(ICP DAS - BMP)
产品描述
▪ Description
Alithane™ ALP-B20 is medical grade aliphatic polyether-based thermoplastic polyurethanes (TPU) loaded with 20% 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-B20 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).
