Melting point of uhmwpe. This thermal-contraction is caused by the melting of included PE crystals. It’s this extremely high molecu-lar weight that gives UHMW-PE an unsurpassed combination of slickness, toughness and chemical resistance. The melting point of UHMWPE usually ranges between 130°C and 270°C, depending on its molecular weight and crystalline structure. Because the resin does not melt-ow or liquefy at its 138 to 142 °C (280 to 289 °F) melting point, the resin retains excellent dimensional stability at temperatures up to 200 °C (392 °F). Compared to the melt-crystallized UHMWPE, the characteristic melting time of nascent UHMWPE is generally longer even in a higher temperature range. Feb 27, 2019 · UHMW (ultra-high-molecular-weight polyethylene) offers a combination of exceptional properties. UTEC has a molecular weight approximately 10 times higher than High Density Polyethylene (HDPE) resins. Its melting point is around 130 to 136 °C (266 to 277 °F), [8] and, according to DSM, it is not advisable to use UHMWPE fibres at temperatures exceeding 80 to 100 °C (176 to 212 °F) for long periods of time. UHMW Overview UHMW-PE (also shortened to UHMW), stand for Ultra High Molecular Weight Polyethylene. This comparatively low melting point is because it has a high molecular weight and forms crystals. . We reserve the right of technical alterations. A full bar means this is the highest value in the relevant set. Thermal stability of the material is the core element in defining its uses. Because of its low coefficient of friction, UHMW-PE The melting point of UHMWPE fibers is around 144–152°C and, generally, UHMWPE fibers are not used at temperatures exceeding 80–100°C for long periods of time. UHMW polyethylene fibers have a melting point between 144 °C and 152 °C and shouldn’t be used for extended periods at temperatures above 80 °C to 100 °C. Click to see its material properties. A definitive quality guarantee is given in our generalconditions of sales. Aug 23, 2025 · UHMWPE softens at about the 130-136 °C range. Unlike conventional wax additives UHMW is a thermoplastic that belongs to the polyolefin group of material. The UHMW-PE fiber contracts considerably when it melts under an unconstrained state. This significant temperature range illustrates that UHMWPE can be tailored for diverse applications by manipulating these variables. Molecular density characterizes polyethylene, with UHMW being the most dense with a molecular weight of 3. Characterized by its high molecular weight and surface composition, this material offers superior impact, abrasion, and wear resistance while maintaining a relatively lightweight structure. A half-full Technical DaTa SheeT UhMW Polyethelyne (UhMW Pe) (Ultra High Molecular Weight Polyethylene) UHMWPE is light weight (1/8 the weight of steel), high tensile strength, and is easily machined. It has a fairly high ductility and a fairly low density among thermoplastics. It’s ideal for reducing wear and friction due to its specialized internal lubrication, reducing maintenance costs and energy consumption while extending equipment life. Custom plastic parts manufactured from UHMW plastic. Title: Physical Properties for UHMW Sheet Description: Physical, Mechanical, Electrical and Thermal Typical Properties. Sep 9, 2016 · Ultra-High Molecular Weight Polyethylene (UHMWPE) has a melting point around 130°C. It is the ideal material for many wear parts in machinery and equipment as well as a superb lining in material handling systems and storage containers. The graph bars on the material properties cards below compare UHMW-PE to: polyethylene plastics (top), all thermoplastics (middle), and the entire database (bottom). Despite this relatively moderate melting point, the unique high molecular weight structure of UHMWPE provides remarkable thermal stability at elevated temperatures. UHMW is simple to machine. May 30, 2020 · UHMW-PE is a thermoplastic, further classified as a polyethylene plastic. Was this article useful to you?
