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.

The team at King Plastics created King Hy-Pact® (Very High Molecular Weight polyethylene), 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, King Hy-Pact® 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.
