DuPont™ Tychem® garments for lightweight protection from chemical and biological hazards.

Not all deadly threats come in the form of fires or weapons. For comprehensive protection against low levels of dangerous chemicals, to toxic gases and biological hazards, industrial workers rely on garments made of DuPont™ Tychem®.

Tychem® is an innovative fabric range comprising multiple barrier layers that help provide protection from chemical and biological hazards. Laminated to Tyvek® for strength, it offers a robust solution with a high level of chemical barrier at uncharacteristically low weight.


Find the right protection


When it comes to chemical hazards, details are everything.


The trusted performance of DuPont™ Tychem® garments begins with our unique chemical barrier fabrics, which undergo testing by third-party labs. We have compiled a comprehensive database of chemical permeation results to support that Tychem® fabrics will stand up to hundreds of chemicals, ranging from toxic liquids and vapors to sarin and chlorine gas.

Garment construction is crucial as well. Secure seams and zippers; proper sizing; the fit and design of hoods and accessories; and even garment colors—all play a critical role in helping keep workers protected on the job. DuPont offers a wide variety of garment styles—from hoods and shoe covers to aprons, coveralls and fully encapsulated suits.



The barrier fabrics and construction methods used in Tychem® garments help prevent penetration and permeation by chemical hazards. As permeation testing is the most sensitive measure, extensive permeation testing assures that every Tychem® garment provides the appropriate level of protection.

Seam Construction

Always select garments with strong, tight seams that are appropriately constructed for your application.

*Serged and/or bound seams are degraded by some hazardous liquid chemicals, such as strong acids, and should not be worn when these chemicals are present.



Garment Style
