Dewatering element Polyethylene suction box cover Plate, which are made of UHMWPE and HDPE material, which widely used in paper industry. UHMWPE and HDPE plastic dewatering element is known for its high dry-film lubricant content. This produces an extremely smooth surface, most importantly resulting in a low friction coefficient a low level of adhesion.
