The ATV manufacturers do a fairly good job of providing frame and under carriage protection for the average trail rider. UHMW-PE is used extensively in the mining industry to protect steel in wear applications, for example, slurry piping. UHMW-PE is very low friction, giving it a slick, non-stick quality. It allows clean, uninterrupted operation/flow in dry, wet and freezing conditions. Materials pass over without adhesion and buildup. Barnacles wipe away from UHMW. SSS off-roads offers a cup washer to recede the bolt heads to minimize damage and keep the skip free of snags. Ultra-High-Molecular-Weight polyethylene (UHMW) is a subset of the thermoplastic polyethylene. Also known as high-modulus polyethylene,(HMPE), or high-performance polyethylene (HDPE), it has extremely long chains, with a molecular mass usually between 2 and 6 million u. The longer chain serves to transfer load more effectively to the polymer backbone by strengthening intermolecular interactions. This results in a very tough material, with the highest impact strength of any thermoplastic presently made. UHMW is odorless, tasteless, and nontoxic. It is highly resistant to corrosive chemicals except oxidizing acids; has extremely low moisture absorption and a very low coefficient of friction, is self-lubricating; and is highly resistant to abrasion, in some forms being 15 times more resistant to abrasion than carbon steel. Its coefficient of friction is significantly lower than that of nylon and acetyl, and is comparable to that of polytetrafluoroethylene (PTFE, Teflon), but UHMW has better abrasion resistance than PTFE.
