Technical Datasheet | Supplied by Mitsui Chemicals
LUBMER™ L5000 by Mitsui Chemicals is a halogen- and PFOA free ultra-high molecular weight polyethylene (UHMWPE) grade. Exhibits low friction and good resistance to wear and chemicals including alcohols, alkalis, oils, hydrogen peroxide, sulfuric and phosphoric acid. Designed for processing by injection molding, extrusion or insert mold for grease-less, light weight gears and bearings. 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 is a self-lubricating, noiseless and food contact acceptable grade with low water absorption. LUBMER™ L5000 provides good moldability, good dimensional stability and electrical insulating properties, high mechanical properties and innovative processability. It contributes to increased production efficiency and total cost reduction in a co-extrusion process. LUBMER™ L5000 can be used for the replacement for PTFE or as a tribology modifier of engineering plastics. Complies with UL 94 HB Flame Rating. Applicable materials for modified LUBMER™ include PA6, PA66, Aromatic PA, POM, PBT, PET, PC, ABS and PPS.
