solutions, such as Tyvek® HomeWrap®, Tyvek® CommercialWrap®, DuPont™ Flashing Systems andTyvek® Protec™, are used to create more comfortable, energy-efficient buildings with fewer chances formoisture damage caused by water buildup.
DuPont is a global leader with Tyvek® protective garments providing superior protection forworkers in industrial and cleanroom applications and for first responders. Companies around the world use
more than 200 million Tyvek® garments per year. Tyvek® garments have been used to support emergency
response efforts across the globe, including the U.S. Deepwater Horizon oil spill cleanup; the Japan 2011

Beyond protecting homes and workers, Tyvek® also is widely used to help protect patients inhealthcare settings. Since its introduction to the medical device industry more than 45 years ago, Tyvek® hasbeen recognized as a standard of excellence for sterile device packaging. Tyvek® earned this distinction
because it provides excellent microbial barrier, strength and protection for medical devices and pharmaceuticalapplications. Tyvek® for medical packaging also helped enable the development of new sterilization methods,
such as low-temperature gas plasma sterilization.
Other applications for Tyvek® include: industrial packaging, active packaging and otherspecialty applications; cargo covers for pharmaceuticals and perishables; envelopes used by the U.S. Postal
Service; and graphics as a substrate for tags, labels, banners, wristbands, maps and the creation of works of art

The history of Tyvek® began in 1955 when DuPont researcher Jim White made a chance

discovery of a new fiber source. A program to develop the new material was set up and a year later DuPont
submitted a patent proposal for strong yarn linear polyethylene. It took several more years for research teams
to perfect the complex manufacturing process, which was based on the flash-spinning technology invented by3DuPont scientist Herbert Blades. In 1965, the new engineered sheet structure was registered under thetrademark name Tyvek®, and in April 1967 DuPont began commercial production. During its first 50 years,
this one-of-a-kind invention has had a tremendous impact across numerous industries, resulting in the creationof new categories of products, such as house wrap, which helped revolutionize home construction; setting newstandards for personal protective apparel; enabling advancements in medical device technology; and playing
an important role in many other applications. DuPont, along with its customers, continues to develop newTyvek® products to meet evolving marketplace needs.
