Gaskets, Seals, O-rings, Elastomers and Resins We provide field-proven materials for the manufacture of semiconductors, where processing steps can involve extremes of both thermal and chemical exposure. Since purity is critical to high semiconductor wafer yield, reducing contamination caused by seal deterioration is a major goal of semiconductor fabricators. We offer a variety of materials that provide reduced contamination and longer life in aggressive wafer manufacturing environments.

Kalrez® perfluoroelastomer parts from DuPont Performance Elastomers Chemical resistance that is nearly universal, coupled with superior high-temperature properties, enables Kalrez® parts to withstand virtually any process media, including plasma with various gases at temperatures up to 327°C (620°F).
Viton® fluoroelastomer parts from DuPont Performance Elastomers The most specified fluoroelastomer, well known for its excellent (400°F/200°C) heat resistance. Viton® offers excellent resistance to aggressive fuels and chemicals and has worldwide ISO 9000 registration.

Pipe, Tubing, Hose, Flanges, Connectors, Couplings and Plumbing Fittings Semiconductor manufacturing involves aggressive chemicals and gases. To ensure safety and purity requirements, DuPont offers a broad range of materials for fluid handling components, vessel and container linings, tools, equipment and systems that come in contact with aggressively reactive, high-purity fluids.
