KetaSpire PEEK polymer chosen for oil scavenger line in Polimotor 2 automotive project

Solvay Specialty Polymers announces that the Polimotor 2 automotive engine project selected a high-performing grade of Solvay’s KetaSpire polyetheretherketone (PEEK) to fabricate an oil scavenger line for the engine’s dry sump modular oil pump system.

Directed by automotive innovator Matti Holtzberg, the Polimotor 2 project aims to design and manufacture a next-generation, all-plastic engine for competitive automotive racing in 2016. Solvay is one of the primary material sponsors for this highly anticipated technical endeavor.

Allegheny Performance Plastics, LLC, a processor of high-performance thermoplastics, machined the 18-in. (45-cm) oil scavenger line from a stock shape available from Texas-based Drake Plastics. The shape was extruded with Solvay’s KetaSpire KT-820 CF30 PEEK, a 30-percent carbon fiber-reinforced grade that retains high modulus and best-in-class fatigue resistance at continuous-use temperatures reaching 240°C (464°F). This is comfortably above the peak oil temperatures in Polimotor 2’s dry sump design, which can reach 138°C (280°F).

The Polimotor 2 project aims to develop an all-plastic, four-cylinder, double-overhead CAM engine that weighs between 138 to 148 lbs (63-67 kg), or about 90 lbs (41 kg) less than today’s standard production engine. Holtzberg’s groundbreaking program will leverage Solvay’s advanced polymer technology to develop up to ten engine parts. In addition to the oil scavenger line, these include a water pump, oil pump components, water inlet/outlet, throttle body, fuel rail and other high-performance components. Besides KetaSpire PEEK, other Solvay materials targeted for use encompass Amodel polyphthalamide (PPA), AvaSpire polyaryletherketone (PAEK), Radel polyphenylsulfone (PPSU), Ryton polyphenylene sulfide (PPS), Torlon polyamide-imide (PAI), and Tecnoflon VPL fluoroelastomers.
