TECAFORM® MT, Polyoxymethylene

TECAFORM® MT is Ensinger’s specially formulated acetal. The material is resistant to multiple cleaning and disinfection agents, and to a number of solvents. It can be steam sterilized by medical industry’s usual methods and will maintain good strength, stiffness, and dimensional stability. Certifications may reference Celcon M-25 resin only.

TECAFORM® MT, Polyoxymethylene (Copolymer Acetal), manufactured by Ensinger is a semi-crystalline thermoplastic offering high strength, stiffness, and toughness.

TECAFORM® MT is typically used in the medical plastics industry and food technology. The material is physiologically harmless and FDA compliant.

TECAFORM® MT is easy to machine, offers no centerline porosity, provides chemical resistance to solvents and fuels, and has excellent mechanical properties.

Modern Plastics stocks an exceptionally large array of TECAFORM® MT rod products in a variety of diameters and colors such as red, blue, green, yellow, rust, gray, hot pink, and black.

All materials are lot-controlled, barcoded and warehoused in clean, controlled climate storage areas.
