Parts and Shapes Made For Demanding Applications
High-performance parts and shapes manufactured by DuPont are the leading choice when resistance, reliability and safety are top-of-mind.
DuPont parts and shapes are used in applications that include undersea oil and gas production, aerospace, transportation, semiconductor integrated circuits manufacturing and life sciences. Both Kalrez® and Vespel® finished parts are precision-made, for long-term performance that can help extend both equipment service life and maintenance intervals.
Parts and shapes from DuPont are supported by our material science experts and the quality assurance of ISO 9001 certification. DuPont engineers work closely with customers to help customers specify, design and deliver molded parts, shapes and seals at sites across Europe, Asia and the Americas. We collaborate with customers to help them meet their individual performance, design, cost, and durability requirements.
DuPont offers a wide range of heat resistant plastics to replace metal, ceramics and other polymers in uses from automotive engines to oil and gas production.
DuPont has a portfolio of chemical resistant elastomers and thermoplastics to match a broad spectrum of challenges – from aggressive automotive fuels to custom industrial equipment.
USES AND APPLICATIONS
- Vespel® in Automotive Parts
- Kalrez® Seals for Semiconductor Processing
- Chemical Processing Seals
- Photovoltaic Manufacturing Seals
- High Pressure Seals
Material Handling Equipment
DuPont™ Vespel® parts have a unique combination of properties that can replace metal, PEEK or ceramic parts in material handling equipment with high temperatures, high wear or no lubrication.
- Centrifugal Pump Parts
- Aircraft Engine and Reverser Parts
- Kalrez® for Aircraft Engine Seals
- Vespel® CR-6100 Boiler Pumps
Sealing Collaboration Pays Dividends in Chamber Cleaning
Chamber cleaning with NF3 / O2 plasma increased maintenance at Spansion due to seal erosion. Kalrez® 9100 parts improved productivity and reduced cost-of-ownership. Kalrez® 9100 parts were successfully qualified in both thin films and dry etch tools.
- Pharmaceutical Seals for CIP and SIP
- Kalrez® parts in API Handling Processes
- Vespel® SP-21 Thrust Washers
Process Instrument Gaskets
By switching from gasket seals of PTFE to custom gaskets of DuPont™ Kalrez® perfluoroelastomer parts in the sensor head of a process instrument refractometer used by the food, pulp and paper and chemical industries, process instrument manufacturer.
O-rings in Pressurized Water Reactor
Due to the combination of extreme temperature, pressure and chemical environments, Kalrez® 0090 was used in a series of mechanical seals employed in the operation of boiler feed pumps for pressurized water reactors.
O-rings for Gas Sweetening Valves
Kalrez® 7090 perfluoroelastomer parts offer an excellent combination of chemical, Rapid Gas Decompression (RGD) resistance , and high temperature resistance for O-ring applications in gas sweetening valves that handle glycol-based solvents.
Kalrez® O-rings for Hydrogen Sulfide Removal
Amine units for hydrogen sulfide removal (H2S) at high temperatures use elastomers like Kalrez® Spectrum™ 6380 FFKM parts for resistance to amines. 6380 helps extend MTBR of valves and pumps in amine service.
- Sealing Solutions for Clamping Systems
Parts for Amine Resistance
A major chemical company switched to Kalrez® Spectrum™ 6380 perfluoroelastomer parts to improve amine resistance & extend mean time between repairs. Improvement of up to 3x in MTBR achieved in a mechanical seal for hot, aggressive amines.
Vespel® Case Rings Boost Pump Efficiency and Safety
The operator of a pipeline in the Southwestern U.S. was searching for a case ring material for pumps that would enable improved operating efficiency, increase equipment reliability and avoid the seizing or galling problems encountered with metal components. The metal components were replaced with Vespel® CR-6100 parts, and the results were impressive.
