Acetron™ C Sterra™ POM-C is a general purpose, copolymer acetal grade with recycled contents that is often favored for its porosity-free nature. This recycled POM-C also exhibits low moisture absorption and excellent machinability capabilities, making it a very versatile material that can excel in a multitude of environments.
As part of the Sterra™ product portfolio, Acetron™ C Sterra™ POM-C contains recycled POM-C and therefore is associated with a significantly lower carbon footprint compared to similar materials derived from non-recycled feedstocks. For details, please refer to the respective environmental datasheet.
