特徵
Sealing blades are made of a special polyurethane sliding part that provides coolant resistance (swelling resistance), a low coefficient of friction, and abrasion resistance.
Unlike rubber wiper blades, this adhesive-fixed design eliminates the need for molds, allowing for free design flexibility.
