In the world of custom plastic extrusion, two of the most common types of materials that you're likely to work with are UHMW and HDPE. UHMW is short for "ultra-high molecular weight polyethylene," while HDPE is short for "high density polyethylene." They both have a number of far-reaching applications and are often used to craft things like tubing, for example. By understanding what makes each one unique, you'll put yourself in a better position to select the most appropriate option while preparing for your next big project. UHMW vs. HDPE: Your Guide The major characteristic that separates UHMW from HDPE tubes has to do with their construction. UHMW is made up of long polymer chains, which is part of what gives it its desirable molecular weight. HDPE, on the other hand, is constructed in a way that plays to its strength-to-density ratio. Where UHMW and HDPE vary significantly has to do with the types of applications they are appropriate for. becaus
