Polypropylene filler is chemical-resistant for containing and absorbing corrosive or reactive spills. Can be incinerated after use to reduce waste. Polypropylene skin is chemical and tear resistant; reduces dust and holds in liquid, even when fully saturated. Specially treated to absorb high concentrations of corrosive liquids, such as 98% sulfuric acid and 30% sodium hydroxide, better than any other absorbent in the market. Pink color is easily distinguishable to prevent improper use and pilfering of spill-response supplies. PIG and the PIG logo are trademarks of New Pig in the U.S. and other countries.
