The DuPont Vespel parts and shapes business has expanded its high-performance portfolio with new Vespel SP-2515 polyimide parts, initially targeted for the global automotive and commercial vehicle industries, where tight tolerances, durability and improvements in energy efficiency are demanded.
Vespel® SP-2515 was recently commercialized in transmission seal rings, which demand low friction, extreme tolerance control over a broad temperature range and long life. The new parts have demonstrated more consistent leakage control than cast iron and other polymeric alternatives. Other applications include engine components for exhaust gas recirculation, where contamination from carbon, dirt or metal debris can cause rapid component failure.
“These new parts improve energy efficiency by reducing friction, weight and cost thereby supporting our strategy to put science to work reducing gas consumption and greenhouse gas emissions,” said Dave Ritchey, global transportation marketing director for DuPont™ Vespel®.
For more than 40 years, the Vespel® parts and shapes business has delivered “big science, part by part, faster than ever before” through high-performance, cost-effective solutions for critical fluid- and motion-control systems. In automotive and commercial vehicles, Vespel® parts are used to manage friction in powertrain applications including emission components, variable valve systems, turbochargers and air induction modules.
