Wiper seal is used on the hydraulic-pneumatic piston rod to remove dust from the external surface of the piston cylinder and prevent sand, water, and contaminants from entering the sealed cylinder.
At present, most of the practical wiper seal rings are made of rubber materials, which are characterized by dry friction. In this way, rubber materials are required to have particularly good abrasion resistance and low compression permanent deformation performance.
