TIVAR® Sterra™ UHMW-PE
- Chemical Family
- PolyethylenesPolyolefins
TIVAR® Sterra™ UHMW-PE shapes are produced from reprocessed industrial UHMW materials and repurposed for use in a variety of industries, such as construction and heavy equipment, agriculture and grain handling, bulk material and parcel handling, automotive, and transportation. As a premium grade 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, and guides, rollers, conveyors, chutes, hoppers, impact plates, and asphalt equipment components. As part of the Sterra™ product portfolio, this material contains recycled content and exhibits a significantly lower carbon footprint compared to similar materials derived from non-recycled feedstocks.
