Description
[DuPont] Initially developed in 1955, this spunbonded, olefin product was trademarked in 1967. Tyvek® is 100% High density polyethylene without any fillers or binders. The fine, white, continuous filaments (0.5-10 microns) are bonded by heat and pressure to form a dimensionally stable, opaque sheet. Tyvek® is chemically stable, lightweight, durable, strong, lint-free, and acid-free. The paper/fabric is resistant to wetting, but it allows transmission of moisture and vapors. It is widely used as a wear resistant, tear resistant, waterproof paper for banners, maps, and envelopes. Applications also include filtration, packaging, bookcovers, interleaving, clean room clothing, protective garments, and carpet backing. Tyvek® is commonly seen as a protective barrier in new housing construction. In museums, the high-strength wrapping material is used a soft, lint-free, waterproof liner in packing crates and display cases. It is available in stiff (Type 10), soft (Type 14) and perforated (Type 16) forms (PACCIN).

- Non-abrasive, tear-resistant envelopes and media sleeves
- Moisture proof liner for cases and crates
- Cover foam pads or line cavities in contour cut foam
- Light-blocking and form-fitting dust covers
- Soft Tyvek® used to make filled bags/snakes to stabilize objects during transport
Risks
- Tyvek® is degraded by direct exposure to sunlight.
- Tyvek may generate static electricity unless treated with antistatic agents.
- Degraded by Freon, Pine oil, turpentine, dichloromethane, Mineral spirits, Ligroin, Kerosene, Toluene.
- DuPont: [Safety Data sheet]
Physical and Chemical Properties
- Resistant to acids, alkalis and most organic solvents.
- Fibers are 0.5-10 microns.
- Neutral pH. Waterproof, acid-free, lint-free, resistant to mold, mildew, and insects.
- Shrinks at 118 oC. Melting point = 135 oC. Maintains toughness and flexibility down to -73 oC.
- Dimensional stability depends on fiber thickness. Lighter weights may elongate up to 25% before breaking.
Working Properties
