Vespel ® SP, SCP & CR Grades & Key Properties

DuPont ™ Vespel ® SP & SCP Polyimide materials are characterized by a ring-shaped molecular structure containing Nitrogen. These grades are one of the highest performing engineering plastics currently available. They will not melt and can operate continuously from cryogenic temperatures to 550°F (288°C), with excursions to 900°F (482°C). Vespel ® SP & SCP parts consistently exhibit superior performance in a variety of applications requiring low wear and long life in severe environments.

Vespel ® SP Grades

DuPont ™ Vespel ® Polyimide SP-1 Unfilled - provides maximum physical strength, elongation, and toughness as well as the best electrical and thermal insulation values.
DuPont ™ Vespel ® Polyimide SP-21 15% Graphite Filled - for increased wear resistance and reduced frictions. SP-21 has the highest mechanical properties of the graphite filled grades.
DuPont ™ Vespel ® Polyimide SP-211 Graphite & Teflon® Filled - offers the lowest coefficient of friction over a wide range of operating conditions. It also has excellent wear resistance up to 300°F (149°C).
DuPont ™ Vespel ® Polyimide SP-22 40% Graphite Filled - has enhanced wear resistance, lower friction, improved dimensional stability (low coefficient of thermal expansion), and stability against oxidation.
DuPont ™ Vespel ® Polyimide SP-3 15% MoS2 Filled - (molybdenum disulfide solid lubricant) for wear and friction resistance in vacuum and other moisture-free environments where graphite actually becomes abrasive.

Vespel ® SCP Grades

DuPont ™ Vespel ® Polyimide SCP-5000 Unfilled - offers a higher modulus and surface hardness and improved dimensional stability. Compared to traditional polyimides, it offers better strength and stiffness at high temperatures.
DuPont ™ Vespel ® Polyimide SCP-5009 Bearing & Wear Grade - provides material solutions for high wear and friction applications under high operating pressure and elevated temperature environments.
DuPont ™ Vespel ® Polyimide SCP-50094 Low Graphite Filled Grade - designed for demanding applications that require high temperature and wear resistance.
DuPont ™ Vespel ® Polyimide SCP-5050 High Graphite Filled Grade - shapes improve high temperature performance and wear resistance to allow for the replacement of metal and graphite parts. SCP-5050 has a Coefficient of Thermal Expansion (CTE) similar to steel.

Vespel ® SP & SCP Key Properties

Excellent Temperature Resistance	High Wear Resistance (Especially SP-21)	Dimensionally Stable
Resistant to Radiation	Extremely Low Outgassing	Relatively easy to machine

Vespel ® CR PFA Grades

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 25 mm (1.0 inch).

DuPont ™ Vespel ® CR-6110 - shapes are a carbon-fiber filled thermoplastic fluoropolymer that have outstanding performance in aggressive wet chemical / plasma conditions and elevated temperatures.

Vespel ® CR PFA Key Properties

Enhanced Creep Resistance vs. Unfilled PFA	Excellent Chemical Resistance	High Modulus
High Thermal Resistance	CR-6110 Excels in Semiconductor Aggressive Chemical & Plasma Conditions	CR-6100 is designed for use in hostile chemical environments in pump and compressor applications.
