TIVAR® ASTL Food Grade UHMW-PE, based on a polyethylene grade with extremely high molecular weight, was specifically developed for tough anti-abrasion applications. TIVAR® ASTL Food Grade UHMW-PE exhibits higher resistance to wear and abrasion and a lower surface resistivity than TIVAR® 1000 UHMW-PE antistatic. The additives used also render this material static dissipative and highly UV-resistant.
