High performance plastic seals for vehicle driveline application

Minnesota Rubber and Plastics (MR&P) custom formulates high performance plastics to meet specific vehicle applications. Materials include PEEK™, Aurum®, Ultem® and Amodel®. MR&P utilizes over 65 years of experience custom designing and molding these high performance plastics for demanding vehicle driveline applications.

Example – seals and thrust washers for vehicle transmissions. The material selected for this application was PEEK™ because it combines a low value for the coefficient of friction with very low wear rates over wide pressure and velocity ranges. During service, these components are immersed in automatic transmission fluid and operate in a temperature range of -40°F to 264°F (-40°C to 129°C). They withstand dry and lubricated tribological contacts with pressures up to 100 psi and velocities of up to 8000 ft/min. Under such intense conditions, materials must be dimensionally and thermally stable to allow for the correct flow of fluid throughout the system.
