Back to Rulon®
Rulon® 123 is a glossy black non-abrasive compound for softer mating surfaces, such as stainless steel. This material has excellent chemical resistance and is FDA, USDA, and NSF compliant. It is less expensive than Rulon J but is slightly less flexible and higher in wear. It has a high resistance to deformation, a low coefficient of friction, and good thermal and electrostatic dissipation. This material has a maximum operating temperature of 550˚F(300˚C).
Notable Material Features
- High compression strength
- Low coefficient of friction
- Excellent abrasion and corrosion resistance while running without lubrication
