Race bibs, or race numbers are often produced on Tyvek paper, so they are less likely to rip during competition. [20] In 2017, the DuPont company merged with another chemical company, The Dow Chemical Company to form DowDuPont. DowDuPont currently manufactures Tyvek at the Spruance plant in Richmond, Virginia, and in Sandweiler- Contern, Luxembourg. In 2018, DowDuPont announced plans to expand the Tyvek production capacity of the Sandweiler-Contern factory.

Keats, Jonathon. "Artist Tom Sachs' DIY Space Program Is Outmaneuvering Elon Musk And NASA With Plywood And Tyvek". Forbes. Q29: Can Tyvek® be laminated? Will the process affect water resistant performance and breathability? A: Tyvek® should not be considered as flame retardant and its flammability is like most synthetic fibers. Tyvek® type 10 has been tested according to ASTM E84-89a with a class A rating. Type 14 Tyvek® has been tested according to 16 CFR 1610 with a class 1 rating. The melting point of Tyvek® is 135°C and the ignition point of high density polyethylene is approximately 400°C. Specific flame-retardant requirements can be met by applying a special coating to Tyvek®. In 2011, fashion retailer and manufacturer American Apparel included white Tyvek shorts as part of its range. [21] Tyvek ( / t aɪ ˈ v ɛ k/) is a brand of synthetic flashspun high-density polyethylene fibers. The name "Tyvek" is a registered trademark of the American multinational chemical company DuPont, which discovered and commercialized Tyvek in the late 1950s and early 1960s.Costa Rica (solely their 20 colones bank note, Z series), [17] the Isle of Man, [18] and Haiti [19] have made banknotes from Tyvek. These banknotes are no longer in circulation and have become collectors' items. A: The traditional dyeing process for cloth is not applicable for Tyvek®. But the surface of Tyvek® can be colored by printing. Like any good question, this has been the subject of vigorous debate on the Internet. Strictly speaking, even hard structure Tyvek is classified only as water-resistant when water exposure is constant, according to the official Tyvek user’s manual. Water-resistance comes as a benefit of Tyvek’s composition and polyethylene’s natural properties, rather than the result of any sort of coating or treatment. A: The antimicrobial requirements of a material depend on the specific industry and application in which it is used.

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). History of Weather Barrier". www2.dupont.com. Archived from the original on 2012-10-05 . Retrieved 2018-11-28. A: Tyvek® can be stored for many years indoors under controlled temperature and humidity. Do not store Tyvek® in direct sunlight. Store Tyvek® vertically on its ends, overwrapped with Tyvek® or polyethylene film. Core plugs should be in place when roll handling. Tyvek® is incredibly light and flexible. It boasts a remarkable strength-to-weight ratio, so coupled with the high strength and recycleability it is therefore an ideal printing substrate for banners and signs. Made of high-density polyethylene fibres (HDPE), Tyvek® is 100% recyclable just like plastic bottles.Plastic Film and Bag Recycling Collection: National Reach Study" (PDF). Moore Recycling Associates Inc.

A: Tyvek® is dimensionally stable from -73°C to 100°C. Under tension, such as in printing or coating operations, we recommend that temperature not be higher than 79°C to avoid deformation of Tyvek®. Tyvek® has no grain direction, is corona treated on both sides to improve ink adhesion and is coated with an antistatic agent to facilitate converting. A: Yes. HP Indigo, UV inkjet, and Latex inkjet can be used to print on Tyvek®. Typical laser (dry toner electrophotography) is not recommended because the high temperature can melt Tyvek®. Water-based and solvent-based inkjet is possible on Tyvek® that has been coated with an appropriate primer.

A: You can write or paint on Tyvek®. General water-based pens are suitable for washable needs, alcohol-based pens are suitable for permanent writing or graffiti-art, and acrylic pigments are also suitable for painting on Tyvek®. Tyvek is used by the United States Postal Service for some of its Priority Mail and Express Mail envelopes. [15] As plastic bag recycling has become more prevalent in the United States, the American Chemistry Council has recommended that plastic film drop-off recycling locations should be able to accept Tyvek.
