Tychem® provides comprehensive chemical protection with permeation technology

Over the last 30 years, DuPont^™ Tychem^® garments are trusted and preferred by industrial workers and lab technicians for reliable protection against chemical hazards. This trust in our garments has been built over decades due to the rigorous performance testing that Tychem^® chemical protective clothing undergoes in third-party labs and being proven in real-life situations where our garments have performed exceedingly well.

At Tychem^® we believe no matter what the challenge, you should not have to compromise on protection.

Permeation testing is the gamechanger

Thousands of industrial workers and emergency responders suit up in our garments to keep them safe from a wide range of toxic chemicals and gases. The unique and innovative Tychem^® fabrics are tested for penetration and permeation against hundreds of chemicals. Penetration is when there is any particle movement through a tear, pore, or defect in the protective fabric. Permeation, on the other hand, is the absorption, diffusion, and desorption of a chemical through a barrier material at the molecular level. The penetration of liquids, gases, and vapors at a molecular level through the material membrane of a solid is permeation.

Permeation tests are best suited for testing liquids, and vapors.

The outside surface of the test fabric is exposed to challenging chemicals. If the chemical passes through the fabric and is detected on the inside surface of the fabric, permeation has happened. The breakthrough time is the duration of time the challenge chemical takes to permeate through the test fabric.

Tychem^® garments are specifically designed to protect against threats ranging from light liquid splash, heavy exposure to toxic liquids and chemicals, gases like sarin and chlorine, as well as warfare agents. The protective material is engineered in such a manner that it prevents penetration and permeation by chemical hazards.

Extensive and rigorous permeation performance testing is conducted at third party labs against hundreds of chemicals at various concentrations. DuPont provides permeation data to assist companies in selecting the most appropriate protective garments. The permeation testing is an assurance that every Tychem^® protective garment provides the appropriate level of protection so that industrial workers and emergency responders can get the job done without worrying about protection.

Sharing is caring

The comprehensive testing makes Tychem^® better and more efficient at protecting industrial workers and emergency responders from harmful chemicals and biohazards. DuPont has compiled a detailed database of chemical permeation results that indicate the performance of Tychem^® protective garments against hundreds of chemicals and gases.

With chemical hazards, details can make a matter between life and death. DuPont has made the permeation performance data public, unlike other garment suppliers. The resource can be accessed on safespec.dupont.com to assist in selecting the most appropriate garments based on your hazard risk assessment.
