本色TPU/PC Biomerics Quadraflex ALC-55D-B20
Product Description:
Quadraflex™ ALE-8*-B20 is high performance aliphatic polyether thermoplastic polyurethane. The polymer is loaded with 20% barium sulfate by weight, is naturally white and supplied in small pellets for ease of processing. The material exhibits excellent mechanical properties, oxidative stability, biocompatibility, elasticity, non--yellowing during aging and softening at body temperature. The resin has consistent melt flow properties making it ideal for extrusion.
Quadrathane™, Quadraflex™, Quadraban™ and Quadraplast™ performance polymers are primarily used in life science and medical applications including vascular access devices, surgical supplies, respiratory devices, tracheotomy devices, and other medical applications. Typical end products include tubing, catheter parts, balloons, and various medical device components. These performance polymers are available in a variety of durometers, radiopacifiers, colors, and custom formulations.
