Tyvek® is a registered trademark of DuPont for its family of tough, durable sheet products made from pure 100% high density polyethylene (HDPE). The sheet is formed first by spinning continuous strands of very fine interconnected fibres, and then bonding them together with heat and pressure.
The result is a bright white spunbonded sheet, which combines a good printing surface with high opacity, chemical resistance and toughness.
Tyvek® combines the best properties of paper, film and fabric and thus makes it ideal for a wide range of applications, in which strong resistance is needed. Depending on the bonding processes, Tyvek® is available in paper-like or textile-like styles.
Type 14 styles are used where barrier, durability and breathability are required. They offer excellent splash
and dry protection against particulate matter and provide an excellent bacterial barrier. The unique low-linting properties, combined with the barrier properties,make Type 14 an excellent material for cleanroom
apparel in pharmaceutical manufacture and electronic device assembly.
