Material Notes:

POM W is a semi-crystalline thermoplastic, which is certified in accordance with the regulatory system DVGW, technical regulations, work form W 270 and therefore, is particularly suited for the safe application within the vicinity of drinking water. The excellent machinability, dimensional stability and chemical resistance of the basic polyoxymethylene polymer remain. It confirms to food regulatory standards in accordance with BfR/FDA. POM W-plastics often serve as construction elements for bottling drinking water machinery.Information provided by CENTROPLAST Engineering Plastics GMBH
