Vespel® CR Product Family
Vespel® CR family provides excellent chemical resistance in refineries or chemical processing.
They offer high-creep resistance for seals, run-dry capability for wear rings for pumps and easy machinability for tight-tolerance parts like ball-valve seats.
CR-6100
A fiber-reinforced fluoropolymer material designed for use in hostile chemical environments with low creep and high thermal resistance. Well suited for seals, wear rings and other components. Available as stock shape rods and tubes from authorized DuPont distributors.
