Vespel extends part lifespan
D
uPont has expanded its Vespel SCP polyimide family with a new product for extended part life in sealing and bearing applications, especially in non-lubricated high-friction environments suited to the polymer's heat and pressure resistance capabilities. Key industries for the shapes include analytical instrumentation, medical devices, aerospace and energy and material handling."Customers are already demonstrating the wide applicability of Vespel SCP-5009 shapes in different industries and sealing applications. An example is a rotor seal used in analytical instrumentation for High Performance Liquid Chromatography (HPLC), where traditional engineering plastics were reported to have deteriorated quickly under thermal cycling at high temperature and pressure. Vespel shapes are proving very effective in this critical application, delivering a tight, close tolerance seal in many aggressive solvents at pressures above 20,000 psi, and higher productivity from the instrument," said Colleen Carson, Global Marketing Manager of Vespel shapes.
