Plastic seals for vehicle driveline applications

Minnesota Rubber and Plastics 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.

This Minnesota Rubber and Plastics’ design is also more cost effective than traditional materials and far more durable over time. These custom designed seals can be combined with other high performance plastic and elastomer components to form a more effective completed assembly.

MR&P offers comprehensive design services including engineering assistance and design review along with materials engineering for a full range of high performance plastics. MR&P’s value added services reduce component assembly time, material usage, multiple vendor sources and capital expense. MR&P also provides rapid mold design, development and prototype services, process engineering and injection, compression, transfer and liquid silicone rubber molding including metal-to-plastics conversions.

Minnesota Rubber and Plastics has over 65 years experience serving the automotive industry. MR&P’s international, corporate-wide quality systems include: ISO-TS 16949, ISO 13483, and ISO 9000 in all facilities. These facilities operate under a corporate-wide Environmental Management System registered to the International Standards Organization series ISO-14001.
