PE-50 is a heavy-duty cutting oil designed for heavy-gauge carbon steel. It is an upgraded version of PE-36N, containing a high concentration of chlorinated extreme pressure additives and synthetic sulfurized additives, along with synthetic anti-wear components, to provide exceptional die life and part finish, and cleaner tools and dies. The high viscosity of PE-50 provides high film strength, even at high temperatures to carry through multiple stages with a single application. Because of the high concentration of extreme pressure agents, PE-50 is also used in coining, extrusion, and other occasional heavy-duty work.
