Wet tear resistant oil absorbent water repellent non-woven fabric
Developed by HeiQ and its partners TWE and BST, Oilguard is an oil-absorbing, water-repelling, non-woven fabric for oil relief efforts. The product is intended for beach protection against oil spills and is applied to the shoreline. The Oilguard fabric is up to 6 yards wide and several hundred yards long and uses selective absorption technologies. This allows for the fabric to absorb crude oil yet repelling the seawater.
HeiQ won the Swiss Technology Award 2010 for Oilguard.
