This chapter contains basic information pertaining to. properties and identification of metal and heat-treating. procedures used for metals. For more specific information on. metal and heat-treating techniques, refer to TM 43-0106. METAL CLASSIFICATION. All metals may be classified as ferrous or nonferrous.
UHMW (Ultra High Molecular Weight Polyethylene) is an outstanding choice for relatively low cost abrasion, impact, and chemical resistance. UHMW provided by Interstate Plastics is also known by brand names including IPX, Polystone, Tecafine, Dyneema, TivarÂ®, Polysteel, GUR, Utec and Mipelon. Known for an extremely high molecular weight, UHMW features an unsurpassed combination of slickness, toughness and chemical resistance. UHMW's molecular weight ranges from 3.1 million to 100 million grams per mole, with an abrasion resistance that continues to improve as molecular weight increases.
UHMW is more of a pimped out teflon (ptfe) It is just as strong, and has a lubricating agent impermiated in its chemical compound making it self lubricating I know UHMW will melt quite easilly but im not sure about ptfe.If using PTFE as a bushing or some kind of abraision resisting pad.UHMW is far superior.HMW is more of a pimped out teflon (ptfe) It is just as strong, and has a lubricating agent impermiated in its chemical compound making it self lubricating I know UHMW will melt quite easilly but im not sure about ptfe.
