TIVAR™ 88 UHMW-PE is a premium glass-filled grade that offers low moisture absorption, a low coefficient of friction and excellent chemical resistance. TIVAR™ 88 UHMW-PE components are designed to combat flow stoppage, prevent dead volume and allow bulk materials to flow freely. For these reasons, this grade is considered the material of choice for the lining of storage and transport containers, hoppers, chutes, tubes, bunkers, conveyors, vibratory pans and stand pipes. Furthermore, TIVAR™ 88 UHMW-PE liners are available in kits and can be self-installed or professionally-installed through our extensive network of global SystemTIVAR™ Engineering partners.
