Material Notes:

Muralen® is based on high molecular weight polyethylene (PE-HMW) and is ideally suited for use in applications that require the generally impressive material properties of polyethylene. Because of its great cut, impact, and shock resistance, this material is often used to make underlays for cutting and punching machines and for ram guards.Special Properties:• High cut resistance• Good shock and impact absorption• Good resistance to chemicals• Good anti-adhesion properties• Approved for use in the food industry (EU and FDA) • Good weldabilityInformation provided by Murtfeldt Kunststoffe GmbH & Co.
