DuPont launches high-performance parts

DuPont Performance Polymers have launched two new high-performance parts that aim to reduce weight and operational cost, and improve fuel efficiency. ‘Kalrez’ and ‘Vespel’ have been developed to combat complex aerospace sealing, wear and friction challenges at high temperatures for 45 years or more. Kalrez perfluoroelastomer parts are used as oil seals in turbine and jet engines and air delivery systems. Vespel parts offer high temperature capability, wear resistance, and low friction to effectively replace metallic materials.
