UHMW-PE – Ultra-high-molecular-weight polyethylene
PE 9000 MoS² - polyethylene
PE 9000 MoS² is an ultra-high-molecular-weight polyethylene (approx. 9.2 million g/mol) plastic that has undergone further processing. Because of the molybdenum disulphide (MoS²) added to it, the material has significantly better wear‑resistance properties. It is recommended for applications entailing a high degree of wear, including conveyors in mechanical wood processing. We deliver PE 9000 MoS² as sheets.
