Ensinger Tecaform™ MT Acetal, Medical Grade (POM)
Categories: Polymer; Thermoplastic; Acetal (Polyoxymethylene, POM); Acetal Homopolymer, Unreinforced

Material Notes: TECAFORM® MT is Ensinger's specially formulated medical grade acetal. The material is resistant to multiple cleaning and disinfection agents, and to a number of solvents. It can be steam sterilized by the medical industry's usual methods, and will maintain good strength, stiffness, and dimensional stability. the material feedstock meets the requirements specified by the FDA, and its code of federal regulations, CFR 21. It has also been fully assessed for biocompatibility according to US Pharmacopeia (USP) Class VI and ISO 10993.
  • Made from FA compliant resin
  • Tested for biocompatibility in compliance with USP Class VI
  • Tested for Cytotoxicity and compliance according to ISO 10993
  • Easily machinable
while used for a great number of medical applications, TECAFORM MT is particularly suited for use as sizing trials in knee, hip and shoulder replacement procedures.
