TIVAR™ 88 ESD UHMW-PE electro static dissipative shapes prevent the build-up of electrical charges in dusty or volatile environments. As a premium glass-filled cross-linked ESD grade, this lining material also exhibits low moisture absorption, the lowest coefficient of friction of all TIVAR™ 88 grades and excellent chemical resistance. TIVAR™ 88 ESD 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 ESD UHMW-PE liners are available in kits and can be self-installed or professionally installed through our extensive network of global SystemTIVAR™ Engineering partners.
