Acetron™ GP POM-C/Ertacetal™ C POM-C is a general purpose polyoxymethylene, copolymer acetal grade that is often favored for its porosity-free nature. These POM-C shapes also offer low moisture absorption and excellent machinability capabilities, making it a very versatile material that can excel in a multitude of environments. Due to these characteristics, Acetron™ GP/Ertacetal™ C POM-C components are used frequently for food contact applications and meet FDA compositional compliance requirements.
