DuPont™ Vespel® CR-6100 is a composite material designed for use in hostile chemical environments. Stationary parts in this composite material meet the following specification per API STD 610/ISO 13709, Centrifugal Pumps For Petroleum Petrochemical and Natural Gas Industries:-46 to 230°C (-50 to 450°F) temperature limits and 2,000 kPa (20 bar; 300 psi) limiting pressure differential per wear part linear measure of 25mm (1.0"). Due to its low creep and high thermal resistance, Vespel® CR-6100 often excels where other chemically-resistant plastics fall short. This makes Vespel® CR-6100 particularly well suited for seals, wear rings and other components used in a variety of devices and operating conditions.
