Hooded coverall with elastics, Tyvek® front, SMS back
100 per box, individually packed.
DuPont Tyvek® 400 Dual. Hooded coverall combining Tyvek® with an SMS nonwoven back panel. Available in white in sizes SM to 3X. 3-piece hood and gusset for optimal fit. Elasticated face, wrists, waist and ankles.
The Tyvek® Dual garment combines Tyvek® on the front with an SMS nonwoven on the back panel. The Tyvek® front provides an ideal balance of protection, durability and comfort. It is permeable to both air and water vapour, yet repels water-based liquids and aerosols. It offers an excellent barrier against fine particles and fibres down to 1 micron in size. It is ultra-low-linting and antistatically treated. Silicon non-added. The large, breathable back panel, made of SMS nonwoven, offers lower protection against particles (down to 3 microns in size) and light water-based splashes, yet high levels of comfort.
Tyvek® 400 Dual is designed for specific applications that demand comfort while helping to provide protection from frontal exposure during brick ceramic firing, foundries and smelting operations, paint spraying or any work involving composite materials, glass manufacturing, and utilities.
