The extended wear life and enhanced performance of the DuPont Vespel SCP part family are said to deliver value and benefits to aerospace systems worldwide.
“Vespel SCP parts provide improved wear resistance at elevated temperatures compared with traditional polyimides,” said DuPont's Mark Forkapa, global aerospace marketing manager. “That's a key reason why they're gaining more and more approvals for use in aircraft systems in wear applications, including bumpers, wear pads, bushings, seals and shrouds. Aerospace OEMs are finding high value in Vespel SCP parts which deliver longer life and improved performance as well as weight reduction. Engineers' confidence in these new materials has been demonstrated by their having been specified on numerous aircraft programmes.”
Seizing on their benefits, aerospace engineers are choosing Vespel SCP parts over traditional non-metallics in many cases. For example, in applications where non-metallic materials have never been widely used, engineers are relying on the high temperature capabilities and wear resistance of Vespel SCP parts to replace metal, thus saving weight and contributing to operational cost reduction. Vespel SCP parts typically weigh 75-80% less than stainless steel and substantially less than aluminium or titanium components.
