5 DuPont Tychem 4000 items we carry (coverall). Manufacturer test data, chemical and barrier results and the standards named on the data sheet.

What DuPont Tychem 4000 is

DuPont Tychem 4000 is The garment shall be constructed of DuPont™ Tychem® 4000 -- a DuPont™ Tyvek® protective fabric laminated with a chemical resistant Dow Saranex™ 23-P film.; Tychem® 4000 is white for high visibility. The manufacturer names these applications: Uses include waste management, hazardous response and nuclear environments. Seams: Seam types on the SafeSPEC pages for this family: Bound, Taped; Serged or sewn*: A seam produced when three threads are interlocked around the raw edges of two pieces of material for a strong, stress-resistant seam. For potential misting exposure of non-hazardous liquids or particle penetration thro. Shelf life per the manufacturer: What is the shelf life of Tychem® 4000 garments? Tychem® garments may be used for 5 years from the date of manufacture as long as all of the following conditions are met: The garment has been stored p.

In the manufacturer's words: "DuPont™ Tychem® 4000 delivers effective protection against a range of chemical environments. Tychem® 4000 utilizes a chemical barrier film laminated to a Tyvek® substrate to provide a rugged and durable fabric that resists abrasion. Tychem® 4000 fabric provides at least 30 minutes of protection against >124 chemical challenges. Typical applications: chemical mixing, hazardous remediation, emergency medical response, paint spraying, and nuclear environments."

Index of codes: > = greater than, imm. = immediate (<10 minutes), nt = not tested, L = liquid, G = gas. Normalized Breakthrough Time (NBT) shown in minutes. *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. Permeation testing on chemicals is in accordance with ASTM F739, Standard Test Method for Resistance of Protective Clothing Materials to Permeation by Liquids or Gases Under Conditions of Continuous Contact. All tests are conducted at room temperature unless otherwise noted. Reported results are Normalized Breakthrough Times defined by ASTM F739 as the time (in minutes) when the permeation rate reaches 0.1 µg/cm2/min. Note: Numbers reported are averages of samples tested. Sample results vary. All DuPont permeation testing is performed by a third party. Transcribed from the reading-order text of catalog p.10; the chemical-warfare-agent rows were not transcribed (superscript footnote markers are fused to the numbers in the text layer).

Manufacturer limitations and warnings

  • Warning: Most Tychem® garments should not be used around heat, flames, sparks or in potentially flammable or explosive environments.
  • These Tychem® 4000 garments have attached socks made of the garment material. These attached socks must be worn inside protective outer footwear and are not suitable as outer footwear. These attached socks do not have adequate durability or slip resistance to be worn as the outer foot covering.
  • Please note that Tychem® fabrics have different permeation performance. Please check DuPont™ SafeSPEC™ for permeation data that meets your specific needs.
  • *Serged and bound seams are degraded by some hazardous liquid chemicals, such as strong acids, and should not be worn when these chemicals are present.
  • *CAUTION: This information is based upon technical data that DuPont believes to be reliable. It is subject to revision as additional knowledge and experience are gained. DuPont makes no guarantee of results and assumes no obligation or liability in connection with this information. It is the user's responsibility to determine the level of toxicity and the proper personal protective equipment needed. The information set forth herein reflects laboratory performance of fabrics, not complete garments, under controlled conditions. It is intended for informational use by persons having technical skill for evaluation under their specific end-use conditions, at their own discretion and risk. Anyone intending to use this information should first verify that the garment selected is suitable for the intended use. In many cases, seams and closures have shorter breakthrough times and higher permeation rates than the fabric. Please contact DuPont for specific data. If fabric becomes torn, abraded or punctured, or if seams or closures fail, or if attached gloves, visors, etc. are damaged, end user should discontinue use of garment to avoid potential exposure to chemical. Since conditions of use are outside our control, we make no warranties, express or implied, including, without limitation, no warranties of merchantability or fitness for a particular use and assume no liability in connection with any use of this information.

  • As of January 2023, all DuPont Personal Protection products are manufactured under specifications that exclude components containing natural rubber latex. Tyvek® 500, Tyvek® 600 and Tyvek® 800 styles made before January 2023 contain natural rubber latex, which may cause allergic reactions in some sensitized individuals. Anyone who begins to exhibit an allergic response during the use of DuPont products should immediately cease using these products and should report it to DuPont at +1 (888) 439-2988 so that an investigation can be initiated.
  • Wear other appropriate PPE such as, but not limited to, respiratory, eye, head, hand, and foot protection based on the hazard assessment.

Does the manufacturer publish chemical test data for DuPont Tychem 4000? Yes: 2 tables on this page (SafeSPEC CHEMICAL RESISTANCE table for Tychem 4000 (as shown on the SL127B product page); 21 Industrial chemicals ASTM F1001 — Permeation data (catalog p.10), column for Tychem® 4000*), copied from the manufacturer. Penetration and permeation are different tests; the guide on permeation versus penetration explains how to read them.

What does the manufacturer warn about DuPont Tychem 4000? Warning: Most Tychem® garments should not be used around heat, flames, sparks or in potentially flammable or explosive environments. These Tychem® 4000 garments have attached socks made of the garment material. These attached socks must be worn inside protective outer footwear and are not suitable as outer footwear.
