TIVAR™ Sterra™ UHMW-PE shapes are produced from re-processed, industrial ultra-high molecular weight polyethylene materials. These recycled shapes are then re-purposed for use in a variety of industries such as construction and heavy equipment, agriculture and grain handling, bulk material and parcel handling and automotive and transportation.
As a premium grade UHMW-PE that is both economical and eco-friendly, TIVAR™ Sterra™ UHMW-PE components exhibit excellent abrasion and corrosion resistance, outstanding impact strength, minimal moisture absorption and a low coefficient of friction. For these reasons, TIVAR™ Sterra™ UHMW-PE is often a favored solution for wear and outrigger pads, strips, rails, guides, rollers, conveyors, chutes, hoppers, impact plates and asphalt equipment components.
As part of the Sterra™ product portfolio, TIVAR™ Sterra™ contains recycled UHMW-PE and therefore is associated with a significantly lower carbon footprint compared to similar materials derived from non-recycled feedstocks.
