INFORMATION & IDEAS
For standard and complex composite seal applications, Kalrez® perfluoroelastomer parts can be designed and molded to your specifications. DuPont has proprietary technology to bond Kalrez® to a variety of materials, such as metal or plastic bonding.
Kalrez® slabs and sheets are available in a variety of standard sizes, thicknesses, and compoundsfor flexible sealing solutions
Kalrez® TriLobe™ Seals improve seal life in dovetail grooves. This design combines the excellent chemical, thermal and plasma resistance of Kalrez® perfluoroelastomer parts with a unique cross-sectional shape.
Reducing wafer contamination from particulates, outgassing and extractables caused by seal deterioration are major goals of semiconductor fabricators. Larger wafers, smallerfeature sizes and decreasing thickness of deposited layers has placed increased emphasis on the need to minimize or eliminate sources of process contamination.
Outstanding resistance to “dry” process chemistry combined with excellent mechanical strength and thermal stability suggests the use of specially formulated FFKM parts for the most critical deposition process sealing applications.
Kalrez® parts withstand attack from more than 1,800 chemicals, solvents and plasmas. The Kalrez® product line has been specifically designed to deliver outstanding performance in aggressive process environments.
Extend part life, reduce weight and cut costs by replacing metal parts and assemblies with Vespel® SCP-5050 and SCP-50094 high temperature polyimide parts for more demanding high temperature and wear environments.
Kalrez® bonded door seal applications provide improved sealing performance versus conventional O-rings by reducing particle generation, extending seal life and minimizing replacement time during preventive maintenance.
Kalrez® parts last longer and seal more effectively than other elastomers due to their exceptional heat resistance. Even after long-term exposure up to 327°C, they retain elasticity and recovery properties better than other high temperature elastomers.
Stock shapes sizes, such as rods, plaques, and tubes are available for machined parts in a wide variety of sizes. View sizes and availability.
AURUM® thermoplastics polyimide resins are melt-processable and can be injection molded or extruded for conversion into parts and shapes. AURUM® resins containing PTFE and processed at high temperatures require AURUM® Processing Precautions.
As alternative drive vehicles evolve, the challenges only multiply. DuPont is working with automotive manufacturers to help them improve efficiency and range in today’s hybrid and electric vehicles, and further the development of the fuel-cell powered vehicles of tomorrow.
Many of today’s vehicle system environments are like a pressure cooker of aggressive chemicals. Very few materials have the right combination of characteristics to withstand that kind of severe treatment. DuPont is at the forefront of the development of the latest generation of high performance materials.
DuPont is working with our auto industry collaborators to help them develop the next generation of sustainable mobility solutions. Together, we’re helping reduce dependence on fossil fuels and lower greenhouse gas emissions to help manage the environmental impact associated with the world’s increasing demand for automotive mobility.
DuPont materials and solutions help automakers control car manufacturing costs while meeting tough regulatory compliance guidelines.
Vehicle weight reduction is a major challenge. While plastics are inherently lighter than metals, lightweighting requires more than direct material substitution. DuPont predictive engineering and design teams work with customers, using insight and high-performance DuPont materials to redesign for lower weight, often integrating functions to cut costs at the same time.
DuPont automotive solutions give automotive engineers a wide range of vehicle design options, including technologies for noise reduction, longer-lasting, more vibrant textiles, more sustainable air conditioning solutions, and more stylish LED systems.
DuPont vehicle safety solutions help increase safety across the whole automotive value chain, from employee safety on the production floor to driver and passenger safety on the road.
Vespel® products are made from a variety of materials (polyimides, thermoplastics, composites and chemically-resistant polymers). These products offer a unique combination of physical properties and design flexibility. Parts are available as custom parts, stock shapes, components or assembles.
AURUM® resin families are thermoplastic polyimides that are melt-processable lending itself to fabrication methods such as injection molding and extrusion.
Authentic Vespel® shapes are the source of machined components, and the relationship between process, size, becomes critical. Therefore, it is important to make certain that the particular shape being used is produced by DuPont in the particular size and composition as was specified during the qualification process.
For Vespel® Custom Parts, DuPont engineers work with part designers to customize the production method and material for desired end-use results. DuPont engineers may recommend fabricating a finished part from Authentic Vespel® stock shapes for prototypes, small quantities or complex geometries.

For Authentic Vespel® stock shapes, rods, plaques, and tubes buy only from a DuPont authorized distributor.
DuPont is working with automakers to develop materials that help optimize engine efficiency. Focus areas include heat and friction management, exhaust gas recirculation, and re-imagining turbocharger technology or injection systems for mainstream vehicle production.
