UHMW (Ultra-High Molecular Weight Polyethylene)
Ultra-high molecular weight polyethylene, commonly known as UHMW or UHMW-PE, is a lightweight and long-wearing engineering plastic material. Many variations of UHMW are available including FDA compliant, Static Dissipative and UV resistant to name a few.
These variants allow UHMW shapes to be machined int parts for a variety of applications. As a distributor, thyssenkrupp Engineered Plastics stocks all grades of UHMW shapes from all the top US manufacturers including Rochling, Quadrant, Ensinger and more.
Features and Benefits of UHMW-PE:
- Excellent abrasion resistance
- Excellent impact resistance
- Very low coefficient of friction
- Chemically inert
- FDA and USDA compliant for food contact
- Causes no unwanted smell, taste, or discoloration; will not stain even with foods like tomatoes
- Easy to machine
- Helps reduce noise
- Highly effective replacement for metal parts

Properties of UHMW-PE:
UHMW polyethylene causes no unwanted smell, taste, or discoloration, and meets FDA and USDA requirements for direct food contact. It is highly resistant to moisture absorption and is chemical resistant, and as such is easy to clean and sterilize using water, steam, detergents, or disinfectants.
UHMW-PE exhibits excellent abrasion and impact resistance, as well as a low coefficient of friction. UHMW parts are ideal replacements for metal parts in many applications, as they can help reduce weight, noise, and cost.
Common Applications for UHMW:
UHMW Machined parts for conveyor lines - UHMW polyethylene is an excellent material of construction for high wear parts in facilities where conveyor line noise is an issue. Packaging machines utilizing UHMW-PE components run quieter, and in some cases may achieve faster conveyor speeds thanks to the material’s low coefficient of friction. The low coefficient of friction also gives UHMW excellent release properties, preventing buildups and bottlenecking on conveyor lines moving food products or other potentially-sticky substances.
UHMW machined parts for replacing metal parts - UHMW-PE has also proven to be a good replacement for metal parts such as large chutes, wear strips, guides, and rollers. It provides excellent performance in packaging equipment applications, and its high abrasion resistance and excellent wear properties give it long working life, even in nonstop or high-cycle operations.
