DuPont™ Tyvek® Marks 40 Years of Energy Efficiency and Protection

Wilmington, Delaware, June 19, 2007

Innovative Applications Help Protect Buildings, People, Products and Critical Documents

DuPont™ Tyvek®, a pioneering nonwoven material that provides an excellent combination of barrier protection, durability and breathability, marks its 40th anniversary as demand continues to be strong in applications where high-performance protection is required.  Combining the best characteristics of paper, film and fabric, Tyvek® is lightweight but still strong, and breathable while resistant to water, a wide range of hazardous materials, chemical degradation and tears.

“DuPont™ Tyvek® revolutionized the selective barrier as the first nonwoven that is not permeable to particulates, mold, and bacteria, while still letting beneficial elements like clean air pass through,” said Matthew L. Trerotola, vice president and general manager – DuPont Nonwovens. “DuPont has a strong tradition of delivering Tyvek® innovations to meet the changing needs of the global marketplace.  As a global leader in selective barrier technologies, we are committed to continue to provide Tyvek® and other technologies to help protect buildings, workers, vehicles, equipment and critical information documents.”

Tyvek® has unique qualities that make it ideal for end uses across diverse industries, with innovative consumer and protection applications.  Although the most commonly known application is DuPont™ Tyvek® HomeWrap® , Tyvek® is also used in protective garments, envelopes, tags and labels, indoor and outdoor signs and banners, sterile medical and industrial packaging as well as bags, maps and car covers.  Additional Tyvek® applications include:

  • Protective garments made of Tyvek® are widely used in manufacturing, laboratory and emergency response settings around the world, providing superior worker protection from hazardous materials.
  • Tyvek® is used in virtually every form of sterile medical packaging for devices and supplies.
  • Tyvek® envelopes have been the preferred choice for the Fed Ex® Pak for more than 30 years.
  • Covers made with Tyvek® have been used to help protect everything from personal vehicles to NASA space station modules during manufacturing, transportation and storage.

DuPont continues to aggressively pursue new and emerging applications for Tyvek®, adding new performance capabilities and introducing new ways to use or work with Tyvek®.  Recent product introductions include:

  • Tyvek® Auto Surface Protection System helps protect the finish of new vehicles during shipping, while allowing paint to fully dry and cure.
  • Tyvek® Brillion® DR and DRC give printers and tag and label manufacturers a greater range of options to enhance the printing and appearance of their products.
  • InkJet Banner Media made with DuPont™ Tyvek® features an advanced coating to ensure compatibility with inkjet printers in the development of wide format signs and banners.
  • Tyvek® AtticWrap™ is the first breathable roofing membrane to create an airtight attic.
  • Tyvek® ThermaWrap™ helps provide increased comfort and reduced energy costs by improving the reflection of radiant energy in wall systems.
  • New DuPont™ Tyvek® Comfort fit design coveralls were designed based on wearer input and provide workers with a significantly more comfortable fit, improved mobility and enhanced durability. 

DuPont introduced Tyvek® in 1967.  The initial discovery was made when a DuPont researcher recognized the potential value of a high strength white polyethylene fiber formed in samples taken from a new DuPont high-density polyethylene process.  A program was established to develop the new material into an engineered sheet structure now registered as Tyvek®, which today is produced at DuPont facilities in Richmond, Va., and Luxembourg.  Tyvek® is 100 percent recyclable.

DuPont – one of the first companies to publicly establish environmental goals 16 years ago – has broadened its sustainability commitments beyond internal footprint reduction to include market-driven targets for both revenue and research and development investment like Tyvek®. The goals are tied directly to business growth, specifically to the development of safer and environmentally improved new products for key global markets, including products that help increase energy efficiency, such as Tyvek®.

DuPont is a science-based products and services company.  Founded in 1802, DuPont puts science to work by creating sustainable solutions essential to a better, safer, healthier life for people everywhere.  Operating in more than 70 countries and regions, DuPont offers a wide range of innovative products and services for markets including agriculture and food; building and construction; communications; and transportation.
