ALE-8*-B30 Biomerics Quadraflex经销商
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.
