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.
USES AND APPLICATIONS
- Vespel® in Automotive Parts
- Kalrez® Seals for Semiconductor Processing
- Chemical Processing Seals
- Centrifugal Pump Parts
- 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.
- Aircraft Engine and Reverser Parts
- Kalrez® for Aircraft Engine Seals
- Pharmaceutical Seals for CIP and SIP
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.
- Vespel® CR-6100 Boiler Pumps
- 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.
- 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.
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.
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® Spectrum™ 6375 O-rings for PTFE replacement
- Natural Gas Sampling and Delivery
