Compatible Machine Model : UNO B104, UNORB104, NOVA RB91/104/120, BOLT RB104/120 MACHINE.Ultra-High-Molecular-Weight Polyethylene (UHMW) is a subset of the Thermoplastic Polyethylene. Also known as High Modulus Polyethylene (HMPE). It has extremely long chain with a molecular mass usually between 3.5 and 7.5 million amu. The longer chain serves to transfer load more effectively to the polymer backbone by strengthening inter molecular interactions. This result gives smooth movement of bunch without any damages.
