New Pig Fat Mat extreme-weight oil-only absorbent mat roll. Sixteen layers of 100 percent polypropylene are thermally bonded to form one highly absorbent mat capable of drinking up huge volumes of oily liquids. Tough, spunbond top layer stands up to heavy foot traffic; won't rip, tear, fray or create a trip hazard, even when saturated. Fast-wicking "diaper action" transfers oil into the absorbent inner layers to keep moisture away from surface. Absorbs and retains oils and oil-based liquids - including lubricants and fuels - without taking in a drop of water. Flame-resistant material won't burn immediately like cellulose mats; melts when exposed to high heat while on the job. Can be wrung out and incinerated after use to reduce waste or for fuels blending. Dispenser box makes mat easy to access, carry and store while protecting contents from dirt and moisture. Easy-tear perforations let you take only what you need, so you use less mat and save money. Extreme-weight Fat Mat construction is ideal for applications that require long life and high capacity. Perforated: every 10-inches lengthwise and centered widthwise. Absorbency: up to 40 gallon per Bag.
