Fluorosint™ 500 PTFE shapes possess a unique combination of stability and wear resistance for sealing applications where tight dimensional control is required. With nine times greater resistance to deformation under load than unfilled PTFE, Fluorosint™ 500 polytetrafluoroethylene exhibits outstanding chemical and hydrolysis resistance and excellent mechanical and tribological properties. Additionally, Fluorosint™ 500 PTFE’s coefficient of linear thermal expansion approaches the expansion rate of aluminum and is 1/4 that of virgin PTFE, which often eliminates fit and clearance problems for designers.
