Tyvek, like Nomex and Kevlar, is another type of versatile and durable synthetic material that was invented by the DuPont Company. Tyvek has excellent wear and abrasion-resistant properties and it is used to make a variety of protective work wear such as: overalls, coveralls, work gloves, wristbands, suits, and shoe covers, etc. Work clothes that are made out of Tyvek are used for hazardous environments and for general, non-hazardous, industrial use. The material offers protection against splashes of water-based non-corrosive acids and pesticides and forms a barrier against dry particulates such as lead dust, asbestos and radiation dust. Tyvek work clothes are worn by workers in many types of industries. These include mechanics, industrial workers, manufacturing workers, painters, and people who work in chemical labs, etc.
Since Tyvek is water resistant and breathable, it is ideal for making covers for automobiles and motorcycles, etc. out of. The material protects against acid rain and salt spray and it also lets trapped moisture to escape, which helps to prevent rot and mildew from forming. Tyvek can also block out 98 percent of the sun''s ultraviolet rays.
The material was discovered in 1955 and it offers the best characteristics and properties of paper, film and fabric all in one material. This unique balance of properties cannot be found in any other type of material. Tyvek fabric is flash spun from high-density polyethylene. It has many favorable properties and characteristics as it is lightweight, smooth, vapor-permeable, water/chemical/puncture/ tear/abrasion resistant, low-lint and opaque. Printing, slitting, cutting, corona treatment and embossing can be done on Tyvek. Other uses of Tyvek include making: strong and lightweight envelopes, sterile medical packaging, outdoor ad posters and banners, labels, schoolbook covers, tags, long lasting maps and guidebooks, workshop manuals, chemical container labels, race numbers for extreme sports runners, frozen food labels, covers for cars, shoes, boats and campers, etc. The material is very breathable, but it will not let water vapor and bacteria to pass through it.
Tyvek superficially is a lot like paper as you can write and print on it and it is available in sheet forms. However, Tyvek envelopes can not be recycled as used paper. DuPont, does however, operate a Tyvek recycling program in the U.S.The man-made material has been used by the U.S. Postal Service for some of its Priority Mail and Express Mail packages and it has also been used as banknotes in some nations.
