VHMW or Very high molecular weight is an excellent choice as an interim material, fitting nicely in it’s properties between HDPE and UHMW. It provides considerable cost savings over UHMW, while offering similar performance characteristics. VHMW is a good choice when increased durability, abrasion resistance and performance is required vs. HDPE, but the properties of UHMW are more than the application requires.
There are many cases in which UHMW is specified for installations where its ultimate abrasion and impact resistance are not necessary. In many cases, the customer’s only alternative was to use standard HDPE, which lacks the durability of UHMW in most applications.
VHMW (Very High Molecular Weight polyethylene), is a unique product designed to be a perfect complement to UHMW and to bridge the wide performance gap between HDPE and UHMW. When used properly, VHMW allows distributors and manufacturers to reduce costs while suffering no performance loss. Naturally, good design practices dictate that new applications should always be tested before full-scale operations begin.
