Made from100% high-density polyethylene fibres, Tyvek® is manufactured in a unique flash-spinning process without the use of binders. Tyvek® is formed by a continuous process from very fine 0.5-1.0micrometer fibres – 50Xsmaller than a human hair. These fibres are first spun and then bonded together by heat and pressure until a solid sheet structure is formed.
Without a doubt, Tyvek® combines all the best physical properties and characteristics of paper, film, and fabric – in one exceptional material. While most products offer water resistance or breathability, Tyvek® offers both. Tyvek® is equally strong and protective wet or dry. It is lightweight, flexible, smooth, particulate free, opaque, and resistant to water, rot &mildew, chemicals, abrasion, and aging.
All Tyvek® styles are acid free with a neutral pH=7. Its unique combination of properties makes Tyvek® ideal for a broad range of applications.
