HAZWIK® High-Visibility Absorbents combine effective absorbency and hazardous-materials messaging in one convenient solution. Surfactant-treated polypropylene picks up a wide range of aggressive chemicals, including hydrofluoric acid. Bright color and printed message alert workers to the presence of hazardous materials and waste. Green coverstock identifies product for proper separation and disposal, and reduces likelihood of linting or tearing. Heavy weight: specifically designed for continuous leaks and larger spills so you use less material. Perforations reduce waste by allowing you to use only what you need.
