Celcon® M-25 yellow (TECAFORM® AH MT)

yellow POM-C medical

Celcon M-25 (TECAFORM MT) yellow is Ensinger's specially formulated acetal, suitable for medical applications. The POM-C 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. It is tested for biological compatibility on the stock shape and can be supplied in a variety of different colors and dimensions. Certifications may reference Celcon M-25 resin only.
