Tyvek® 500 HV garments are mainly composed of flash spun polyethylene, providing an ideal balance of protection, durability and comfort. Thanks to their nonwoven structure, they are permeable to both air and water vapour, yet repel water-based liquids and aerosols. They offer an excellent barrier against fine particles and fibres, are ultra-low linting and antistatically treated on the inside. Their bright fluorescent orange colour combined with silver grey retroreflective bands make them highly visible during the day as well as in the night (when exposed to a light source). Applications for Tyvek® 500 HV garments include rail, road, mining, waste handling, undergrounds, ports, airports and construction.
