Description

Tyvek
Credit: Garry Harrison

[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). Tyvek® envelopes are used to store archival documents, photographic negatives or other small items. Tyvek® 6060 or 1073 has been recommended for paper-like labels; however, a sample should be tested before use to ensure that the ink does not soak through and transfer to the object below (Tetreault 2017).

Applications

Support for textiles
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

Type 10= paper-like, hard structure, area-bonded, smooth pattern, stiff
Type 14= fabric-like, soft structure, point-bonded, embossed pattern, flexible
Tyvek® is tear resistant but is easily cut with scissors or a knife. Water vapor can pass Tyvek, but liquid water cannot.
Tyvek® can be bonded by ultrasonic welding or dielectric bonding. Heat sealing causes puckering as it often bonds to itself.
Dupont recommends water-based adhesives (starch, dextrin, animal glues, PVAC) over any synthetic solvent-based adhesives.

Forms/Sizes

Tyvek® sheets are available as 30", 36” and 60” wide rolls in length up to 100 yds long. Thicknesses can range from 6.6 mils (1025=hard, 1443R=soft), 7.3 mills (1020=hard) and 7.6 mils (14M=soft)

Various sizes of pre-made folders, media sleeves, envelopes and expansion envelopes.
