What plastic holds up when parts face constant impact, friction, and wear?
In this episode of Ask an Engineer, Iain explains UHMW (ultra-high molecular weight polyethylene) — an engineering plastic known for exceptional toughness, abrasion resistance, and low friction.
Often used for guide rails, wear strips, mounting blocks, and sliding supports, UHMW helps reduce wear and metal-on-metal contact inside enclosures.
Inspired by the spirit of observation (and a little David Attenborough narration), we take a closer look at one of the toughest plastics used in engineering design.
