UHMW Plastic Sheet

UHMW vs HDPE

Both UHMW and HDPE, are types of polyethylene plastic that can be used in various industrial applications. It’s important to understand the similarities and differences before purchasing to distinguish which material is more suitable for your needs.

At a molecular level, HDPE has a high-density makeup, meaning it doesn’t absorb much liquids. It can also be easily shaped and welded using thermoplastic equipment. It’s a low-cost, durable, abrasion, and chemical-resistant plastic material. HDPE is often used as a vessel or container, or for marine applications. 

On the other hand, UHMW is also low-cost and primarily used for applications that require extreme strength and abrasion resistance. This is an extremely popular plastic for wear industrial applications that require constant friction between moving parts over time. It’s also easy to fabricate and machine, but it's more difficult to form specific shapes or to weld.

There isn’t one choice that’s better suited to every application, but more about choosing which option is a better fit for your specific scenario. If you are unsure what plastic sheet to use for your application, please contact us.

UHMW vs Acetal

The primary difference is machining the two materials. UHMW is soft and more difficult to machine compared to Acetal due to its slippery form and it also suffers from thermal expansion. Acetal is a harder material with high mechanical strength and rigidity. It machines close to tolerance and performs better in precise (typically small) parts. They are both good alternatives to metal, with UHMW being the more economical option.
