Tyvek® products

DuPont™ Tyvek® is a family of tough, durable sheet products made from high-density polyethylene (HDPE). Continuous, fine, HDPE fibers are spun into a sheet, then bonded with heat and pressure to interconnect the fibers. Depending on the bonding process, Tyvek® has paper-like styles (hard structure) or textile-like styles (soft structure).

Both hard structure and soft structure are easily convertable, e.g. printable, sewable and glueable; however, hard structure styles and soft structure styles look, feel and perform differently.

Hard structure (Type 10, identified by style numbers beginning in 10 or 41) is paper-like, smooth and stiff. Compared with soft structure is stronger and smoother. It can also hold water and can maintain a three-dimensional shape when folded or sewn (dead-folded).

Soft structure Type 14 is soft, fabric-like and drapeable. Sewing, gluing and, to a limited extent, ultrasonic seaming and heat sealing, may be used in fabricating these styles. Type 14 styles are used where barrier, durability and breathability are required. They offer excellent barrier against particulate matter and can provide an excellent bacterial barrier. The unique low-linting properties, combined with the barrier properties, make Type 14 an excellent material for cleanroom garments and pharmaceutical manufacturing garments.
