Vespel® and Kalrez® parts in aircraft engines

DuPontTM  Vespel® parts offer improved part life, lower wear, reduced weight and lower overall cost compared with parts made from metal or older polymers. Vespel® SCP-5050 and SCP-50094 parts combine proprietary polyimide polymer with advanced filler technology to outperform other polyimides. They deliver superior heat and solvent resistance and their compression strength at 5% strain is about 60% higher.

Kalrez® perfluoroelastomer parts can withstand extreme chemical and thermal environments in highly aggressive aircraft lubricants.
