LUBMER™ L4640

LUBMER™ L4640 by Mitsui Chemicals is a filled, halogen- and PFOA- free, ultra-high molecular weight polyethylene (UHMWPE) grade. It is a self-lubricating, noiseless and food contact acceptable grade with low water absorption. Exhibits low friction and good resistance to wear, alcohols, alkalis, oils, hydrogen peroxide, sulfuric and phosphoric acid. Applicable materials for modified LUBMER™ include PA6, PA66, Aromatic PA, POM, PBT, PET, PC, ABS and PPS. LUBMER™ L4640 provides good moldability, good dimensional stability and electrical insulating properties, high mechanical properties and innovative processability. It effectively improves sliding property in low dosage, better than PTFE or molybdenum disulfide. It also improves abrasion resistance for higher durability and robust material. It contributes to increased production efficiency and total cost reduction in a co-extrusion process. LUBMER™ L4640 can be used for the replacement for PTFE or as a tribology modifier of engineering plastics. Designed for processing by injection molding, extrusion or insert mold for grease-less, light weight gears and bearings.
