Introduction

ArothaneTM ARP-W is medical grade aromatic polyether-based thermoplastic polyurethane (TPU) loaded with 30-50% Tungsten as radiopacifier. It exhibits exceptional radiopacity compared to Barium Sulfate especially for small-dimension or thin-walled devices. ARP-W maintains superior mechanical properties, excellent hydrolytic resistance, oxidative stability, chemical resistance and biocompatibility of clear grade ARP. It is typically a material of choice for guidewire coating or extrusion process.

Biocompatibility

ArothaneTM ARP-W pellets passed the Hemolysis test (ISO 10993-4), MEM Elution test (ISO 10993-5), Intracutaneous Irritation test (ISO 10993-10：2010 & 10993-23：2021), Dermal Sensitization test (ISO 10993-10：2010, 2021), Acute Systemic Toxicity test (ISO 10993-11) and in vivo Pyrogen test (ISO 10993-11, USP <151>.)
