Tyvek 1073D 75gsm
Tyvek® 1073D is paper-like (hard structure)
Antistatic and corona treated.
DuPont™ Tyvek® is very fine polyethylene fibers (seven times finer than human hair) that are bonded by heat and pressure to create a printing substrate that isn’t paper, fabric, or film, but combines the best properties of all three.
It is produced in “hard” and “soft” structure types. Products beginning with a 10 are “hard” structure products. For instance, Tyvek® 1037D is a hard structure. These products are considered “hard,” as they are smooth, stiff, non-directional paper-like substrates with good printability.
What’s so special about DuPont™ Tyvek®?
DuPont™ Tyvek® gives a more distinctive look, to anything you print, than common paper. It feels more natural and has far better flat, precision folding qualities than synthetic films.
Although it isn’t a fabric, it can easily function as one. In fact, the physical properties common to both types of DuPont™ Tyvek® make them ideal substrates for most of your printing and converting applications.
OUTSTANDING CHEMICAL RESISTANCE
Tyvek® products are inert to most acids, bases and salts. Prolonged exposure to oxidizing substances, such as concentrated nitric acid or sodium per sulphate, will cause some loss of strength.
GOOD DIMENSIONAL STABILITY
Sheet dimensions change less than 0.01% between 0 and 100% relative humidity at constant temperature.
The flammability characteristics of Tyvek® are similar to those of most synthetic fibres. When exposed to a flame, Tyvek® shrinks away rapidly. It will melt at 275°F (135°C), and its auto-ignition temperature is 750°F (400°C).
Hard structure products are rated class “A” when tested in accordance with ASTM E-84-89a, a test for flame and smoke development.
Tyvek® with flame-retardant coatings are available through distributors.
Tyvek® brand of protective materials has outstanding flexibility and exceeds 20,000 folding cycles when tested on an MIT flex tester (TAPPI method T-423) without pre-scoring.
Tyvek® is composed of continuous fibres, hence it does not generate a significant amount of lint particles. This makes Tyvek® an excellent choice for cleanroom applications.
LIGHTWEIGHT AND STRONG
Tyvek® hard structure products are strong and tear resistant yet weigh only half as much as paper. For this reason, they are very popular in packaging and mail applications.
SUPERIOR MOISTURE RESISTANCE
The physical properties of Tyvek® withstand the effects of water. It is equally strong wet or dry.
Tyvek® meets the saltwater immersion test for British Standard 5609.
Under normal conditions, Tyvek® remains neutral. Elevated temperatures in excess of 220°F (104 C) will cause width loss and deformation.
Compared with most textile fabrics, the air permeability of Types 10 and 14 is low. Moisture vapor transmission is much higher than that of plastic films and similar to that of coated papers.
ROT AND MILDEW RESISTANCE
Tyvek® is mould and mildew resistant. It shows no degradation after being buried in soil for an extended period like paper products or coated synthetics.
Tyvek® resists soiling and absorption of oils and greases. Tyvek® can be washed with a mild detergent. Heated drying is not recommended.
Tyvek® “B” grade has a neutral pH of 7 which makes it excellent for archival quality because it does not have antistat or corona treatments. Tyvek® is also lignin free.
