Meltblown Hazmat Pillows measure 18"L x 8"W x 2"H, with 20 pillows included per box. MBT's spunbond-covered pillows are flexible drip catchers filled with chopped, universal scrap, for use under leaky machinery or horizontal drums. Hazmat pillows are designed to absorb most aggressive (acidic/caustic) and non-aggressive fluids (oil, water, glycols, etc.), which penetrate the spunbond covering and spread throughout the fluffy polypropylene filler to protect floors and equipment. MBT's pillows can be placed in tight spots where everyday leaks occurr, and they are also useful as the main absorber for emergency spills on cement or concrete.
