Description
Black UHMW (Ultra-High Molecular Weight Polyethylene) Sheet is an exceptionally durable plastic known for its extreme abrasion resistance and ultra-low friction properties. This engineering-grade material offers superior wear resistance compared to standard HDPE, making it ideal for demanding applications where parts slide, rotate, or experience heavy wear. The black color contains carbon black for enhanced UV resistance, making it perfect for both indoor industrial use and outdoor applications.
ShapesPlastics Black UHMW Sheet combines the lowest coefficient of friction of any plastic with outstanding impact strength and chemical resistance. Self-lubricating and virtually maintenance-free, UHMW won't rust, corrode, or absorb moisture. It operates quietly, reduces wear on mating surfaces, and performs in temperatures from -200°F to 180°F. The black color hides dirt and wear while providing superior outdoor durability, perfect for industrial environments and heavy-duty applications.

Frequently Asked Questions
What's the difference between UHMW and HDPE?
UHMW (Ultra-High Molecular Weight Polyethylene) has significantly better wear resistance and a lower coefficient of friction than standard HDPE. While both are impact-resistant and chemical-resistant, UHMW is the superior choice for high-wear applications like wear strips, guides, and sliding surfaces. HDPE is more economical for general-purpose applications.
Why choose black UHMW over white UHMW?
Black UHMW contains carbon black which provides enhanced UV resistance for outdoor applications and hides dirt, grease, and wear better than white. Choose black for outdoor use, industrial environments, or applications where appearance in dirty conditions matters. Choose white for food contact applications or clean room environments where visibility is important.
Does UHMW need lubrication?
No, UHMW is self-lubricating due to its ultra-low coefficient of friction. This eliminates the need for oils or greases in most applications, reducing maintenance and preventing contamination. The material's natural lubricity makes it ideal for dry-running applications and environments where lubricants attract dirt or aren't desirable.
Can UHMW be machined or fabricated?
Yes, UHMW can be machined using standard tools, though it requires sharp cutting edges and proper techniques due to its toughness. It can be cut, drilled, milled, and turned. However, UHMW is difficult to bond with adhesives - mechanical fastening is preferred. It can also be welded using specialized plastic welding techniques.
