Innovation and science company, DuPont South Africa launched its Tyvek Classic Xpert superior chemical and particle protective suit at the Electra Mining Africa expo last month.
The garment, which is manufactured by DuPont, in Luxembourg, is an improvement on the DuPont Tyvek Classic protective suit, which offers particle and chemical protection.
DuPont Tyvek marketing manager Lizette Kasselman says the company made enhancements to the suit, which include improved seams owing to a new patent pending seam technology.
“This offers superior liquid protection and passes the new and more stringent type-six norm against liquids. It also offers extra parti- culate protection, which is six times higher than Tyvek Classic and ten times higher than micro- porous film garments,” she explains.
Kasselman states that the new technology has also raised the bar in particulate nominal protection factor, which now reaches a class 2 within the EN 1073-2:2002 standards.
“Tyvek is known for its breathability owing to DuPont’s unique technology. Tyvek Classic Xpert will continue to offer breathability to its users and will ensure a more comfortable working experience.
Microporous film only offers protection against liquids and particle exposure if the film remains intact. When abrasion occurs during standard working procedures, the finding is that the film lifts, breaking the protection barrier. This exposes the wearer to hazards and also increases heat stress because the fabric is not breathable. The film traps heat, causing the suit to become hot and uncomfortable,” Kasselman explains.
She states that the Tyvek Classic Xpert offers enhanced protection against a range of threats, including water-based chemical liquid splash, asbestos, pharmaceutical radioactive particulates and biological hazards.
“The ergonomic design has been improved to provide exceptional freedom of movement and to ensure a precise fit and maximum protection,” she notes.
DuPont also launched its Tychem TK suit, which offers level-A protection against a broad range of toxic and corrosive gases, as well as liquid and solid chemicals, two months ago.
“The Tychem TK suit acts as an encapsulation device, offering the wearer maximum protection,” she says.
Kasselman further adds that the high-performance chemical barrier fabric from which the suit is manufactured is suitable for industrial, hazardous-materials and domestic-preparedness applications.
“The suit is made from durable fabric that is puncture- and tear-resistant, giving it high protection and chemical-barrier properties. It has been tested against 260 chemicals, with no observed breakthrough after exposures of up to eight hours,” she notes.
She adds that the suit is lightweight, easy-to-wear and an alternative to conventional reusable suits.
