WebUltra-high-molecular-weight polyethylene (UHMWPE, UHMW) is a subset of the thermoplastic polyethylene. Also known as high-modulus polyethylene, (HMPE), or high-performance polyethylene (HPPE), it has extremely long chains, with a molecular mass usually between 3.5 and 7.5 million amu. The longer chain serves to transfer load more … WebHDPE 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.

WebIt provides considerable cost savings over UHMW, while offering similar performance characteristics. Redco™ 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. WebAnyway, UHMW is a ridiculously long version (like millions) of this chain. This long chain gives the material its strength and toughness as there are fewer grains when compared to other materials. UHMW is white in color and easy to machine. Its coefficient of friction is very low (0.15 -0.20 static; 0.12-0.20 kinetic) when used on steel. two ga senators
