Features:
DuPont™ Tyvek® 400 Dual TG. Hooded coverall combining Tyvek® at the front with a SMS nonwoven on the back panel. Available in sizes SM to 3X. Attached Tyvek® under gloves. Attached Tyvek® socks. 2-piece hood and gusset for optimal fit. Elasticated hood and waist. White.Tyvek® front provides an ideal balance of protection, durability and comfort. It is permeable to both air and water vapor, yet repels water-based liquids and aerosols. It offers an excellent barrier against fine particles and fibres down to 1 micron in size on the Tyvek® front. It is ultra-low-linting and antistatically treated. Silicone non-added. The large, breathable back panel, made of SMS nonwoven, offers lower protection against particles and light water-based splashes, yet high levels of comfort.
Applications:
Tyvek® 400 Dual TG is designed for specific applications that demand comfort while helping to provide protection from frontal exposure during applications such as mixing/handling of chemicals* in chemical industry and for EV battery manufacturing in particular, as well as paint spraying and tasks involving fine hazardous particles or composite materials.Thanks to the taped underarm seams on the upper body, it offers increased protection also for the chemicals/products/process against potential contamination from the wearer or from garment seams during the typical work activity.*The user must ensure suitable reagent to garment compatibility before use. Please refer to chemical permeation data available in SafeSPEC™ to determine the level of protection needed.
Benefits:
Protective suits may look the same, but only from a distance. Check out DuPont Tyvek® material advantages over Microporous Film and SMS
Permeation = a measure of chemical barrier performance. Permeation is invisible, but it may strike after a certain period of time if you are not sufficiently protected
Thanks to its unique structure, Tyvek® is a superior and safe barrier in terms of permeation resistance.
Microporous Film may give the perception of good liquid protection because of repellency properties when in reality chemicals quickly permeate through.
BEFORE & AFTER 10 CYCLES OF ABRASION: EN 530 – METHOD 2
Hydrostatic Head determines the resistance of a fabric to water penetration under slight pressure. A Hydrostatic Head of 100cm means that a fabric could hold a column of water that is 100cm tall.
Prior to the abrasion test Microporous Film offers the best resistance to liquid pressure. But after just 10 cycles of abrasion, its performance takes a spectacular dive, while SMS is less affected but starts from a much lower performance level, and Tyvek® continues to protect.
THE SUIT INWARD LEAKAGE TEST – EN ISO 13982 - 2
This test essentially determines the barrier efficiency of the suit when challenged with sodium chloride particulates of a defined size distribution.
Type 5 test allows up to 15% inward leakage of particulates in the suits but who wants to accept this hazardous particulate environment?
NOMINAL PROTECTION FACTOR - EN 1073-2
A suit which offers the highest protection to the fine particulates will have LOW inward leakage, and thus a HIGH nominal protection factor.
Tyvek® Labo and Tyvek® Classic Plus meet Class 2.
The nominal protection factor is between 50 and 500.
DRY LINTING PROPENSITY BS 6909
(method for generation and counting of the airborne linting propensity of fabrics in the dry state)
Tyvek® is the ideal material for application needing low linting (e.g: paint, pharmaceutical applications). By nature of its continuous strong high density polyethylene fibers it does not shed fibers.
Ret = the measurement of the resistance to evaporative heat loss. The lower the Ret value, the less resistance to moisture transfer and the more breathable the fabric.
SMS fabric with their open structure shows the best breathability performances but we know their protection performance is limited. Tyvek® offers the best balance between comfort and protection.
With their open structure, SMS coverall removes better the humidity than Microporous Film, by far.
Tyvek® meets quite good performances during sweating and recovery phase. Microporous Film is the material that takes the longest time to remove humidity.
When selecting a garment, carefully check the quality of the seams, as they contribute to the overall protection of the garment.
Not all seams are tight
Definition of tight = close
Tightness = so tightly made that liquids or gas cannot enter or escape.
Based on permeation and hydrohead test results, we can say that:
