Material Notes:

CENTRODAL GL has good dry running and emergency running properties. During the modification of POM + PE, a PE-UHMW is incorporated to the basic polyoxymethylene polymer. It leads to an improvement of the friction and dry sliding behavior. Applications include bearing bushes, structural components subjected to dynamic loads, and sliding plates.
