What is DuPont™ Tychem®?

DuPont™ Tychem® is a specialized protective fabric designed to guard against chemical and biological hazards. It combines multiple barrier layers laminated to DuPont™ Tyvek® material, creating a lightweight yet highly effective protective solution.

DuPont™ Tychem® garments are used across industries where exposure to hazardous substances is a concern, from industrial chemicals to toxic gases and infectious materials.

How DuPont™ Tychem® Protects You

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.

Fabric: The First Line of Defense

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

Penetration

Bulk movement of a material through a pore, gap or defect in the barrier fabric.

Permeation

Movement of a material through barrier fabric on a molecular level.

Seam Construction: Where Protection Holds Together

Choosing the right seam type helps ensure the garment performs as intended for your specific application.

Serged or Sewn

Threads interlock around the raw edges of two pieces of material. Strong and stress resistant.

Bound

Tightly sewn with a reinforced outer binding. For potential misting exposure to non-hazardous liquids or particle penetration.

Taped

Sewn and taped to provide strong resistance to chemical splashes and physical stress.

Double Taped

Sewn and taped on the inside and the outside for strong resistance to chemicals and physical stress.

Garment Style: Designed for Complete Protection

DuPont™ Tychem® garments are available in a wide range of styles to match different job requirements from basic protective wear to fully encapsulated suits for high-risk environments. Proper fit and design are essential to ensure full coverage and compatibility with other PPE.

Respirator Fit Hood

Designed with a longer zipper for complete coverage of the neck area.

Standard Faceshield

Provides sufficient space for mask-mounted regulators and essential breathing equipment.

Attached Socks

Attached socks with outer boot flaps help prevent liquid pooling into chemical boots.

Why Choose DuPont™ Tychem®?

Provides protection against a wide range of hazardous chemicals, including toxic liquids and gases.

Lightweight & Durable

Engineered for strength while maintaining comfort during extended wear.

Proven Performance

Tested against hundreds of chemicals through third-party permeation testing.

Multiple Protection Levels

From light splash protection to fully encapsulated HazMat suits.

How to Choose the Right DuPont™ Tychem® Coverall?

Type of Chemical Exposure

Identify the substances you’re working with—liquids, vapors or gases. Different DuPont™ Tychem® fabrics provide different levels of resistance depending on the chemical.

Liquid vs. Vapor Protection

Light splashes → Lower-level protection (e.g., Tychem® 2000)
Hazardous liquids or vapors → Higher-level protection (e.g., Tychem® 6000 or 10000)

Exposure Duration

Longer exposure times require higher barrier performance and more durable garment construction.

Fit & Garment Design

Proper fit ensures full coverage and compatibility with other PPE such as gloves, respirators and boots.

Donning guide for standard Tychem® protective coveralls

Proper donning helps prevent chemical exposure risks.

Verify the garment chosen is the correct size and appropriate for the task. Unfold and unzip garment; visually inspect to ensure it is free of any defects (tears, holes, etc.). Don inner gloves as appropriate.
Remove footwear. Carefully insert your foot into the garment leg and through the ankle opening or into attached sock* (if present). Repeat with the other foot and don chemical boots. If the garment has boot flap covers, pull them down over chemical boots.
Pull coverall up and insert one arm into sleeve and guide hand through wrist opening or into attached outer glove (if present). Repeat for other arm. Zip coverall up halfway.
Don additional PPE according to manufacturer’s instructions and site safety procedures as appropriate, e.g., respirator and protective eyewear. Pull the hood (if present) over your head and carefully zip the coverall fully to chin.
Close and secure the flaps over the zipper, including the chin flap (if present). Don outer gloves where appropriate.
Don any final PPE as appropriate, e.g., hard hat. Stretch to ensure coverall fits appropriately and provides range of motion required for task.

Doffing guide for standard Tychem® protective coveralls

Reduce exposure risks during removal by doffing properly.

Carefully remove hard hat (if worn). While standing, detach chin and/or zipper flaps (if present) and then unzip the garment.
Peel the hood (if present) off your head and roll down away from your shoulders to avoid contaminating your inner clothing or skin with the outside of the garment.
Remove your arms from the sleeves one at a time, while removing outer gloves according to manufacturer’s instructions and site safety procedures, being careful to avoid cross-contamination of inner clothing or skin.
Lower/roll the garment down below your hips and sit down if possible. Do not touch the outside of the garment as it may be contaminated.
Remove your chemical boots. Touching only the inside of the garment, pull the garment off your legs and feet. Carefully take the garment away from the doffing area and dispose of it according to your disposal policy
Doff respirator, protective eyewear, inner gloves and/or any remaining PPE according to manufacturer’s instructions and site safety procedures.
