New Pig Heavyweight Absorbent Mat Pads — 15 x 20 in, 100-Count Universal, ~22 Gal/Bag

New Pig Heavyweight Absorbent Mat Pads overview

The New Pig Heavyweight Absorbent Mat Pads are universal PIG mat pads built for the everyday drips, leaks, and spills of a working shop. Each 15 in x 20 in pad absorbs about 28 ounces of liquid — roughly 22 gallons across the 100-count bag — soaking up oils, water, solvents, and coolants alike. What sets the heavyweight apart is the build: eight layers of 100% polypropylene, thermally bonded, so the mat won't rip, tear, or fray even when fully saturated, and you can pick up a soaked pad in one piece. A dimple pattern speeds wicking, and the pads are perforated to tear down into 10 in x 15 in sections. See our best spill kits guide and the spill control collection.

A few useful details. These are universal pads — they absorb common oil- and water-based liquids, so for oil that must shed water you'd choose oil-only pads instead, and for water-based-only jobs there are dedicated options. They're flame-resistant (the polypropylene melts under high heat rather than burning like cellulose) but not fireproof, and they're not static-dissipative mats for fuels. The fine fibers leave no residue, and the dark-gray color hides grime. They're the natural refill for bucket and drum spill kits — restock the New Pig KIT21 bucket or KIT236 drum — and pair with absorbent socks to dam a spill. For aggressive chemicals, use a HazMat or neutralizing kit like the KIT318 instead.

Where they fit

They're the general-purpose absorbency workhorse — wiping drips and leaks, lining machine bases and workbenches, catching overspray, and cleaning spills across shops, garages, manufacturing floors, and maintenance bays. The 100-count bag keeps a supply on hand and restocks your spill kits. Where they're not the tool is oil-on-water (use oil-only pads) or aggressive chemicals (use a HazMat kit). Keep the right PPE nearby — our chemical-resistant gloves and solvent respirator cartridge guides cover protection, and a first-aid kit should be close.

Frequently asked questions

What do these mat pads absorb?

They're universal PIG mat pads, so they soak up common industrial liquids — oils, water, solvents, and coolants. Universal sorbents absorb both oil- and water-based spills, unlike oil-only pads that repel water.

How much does each pad absorb?

About 28 ounces per pad, which works out to roughly 22 gallons for the full 100-count bag. The multi-layer construction and dimple pattern pull liquid in fast for quick cleanup.

What makes them "heavyweight"?

Eight layers of 100% polypropylene are thermally bonded together, making a strong mat that won't rip, tear, or fray even when fully saturated — you can pick up a soaked pad without it falling apart, unlike thin or cellulose mats.

What size are they, and how many come in a bag?

Each pad is 15 in x 20 in, with 100 pads per bag. They're perforated so you can tear a full pad down into smaller 10 in x 15 in sections to match the size of the drip or spill.

Are they flame-resistant or fireproof?

They're flame-resistant, not fireproof — the polypropylene melts when exposed to high heat rather than igniting immediately the way cellulose mats do. That's a resistance to easy ignition, not fireproofing, and these are not static-dissipative pads for fuels.

Can I wring them out and reuse them?

Yes. The mats can be wrung out to recover liquid and reused, and they can be incinerated after use to reduce waste or for fuels blending, subject to your waste and environmental rules.

Do they leave residue behind?

No. The fine fibers don't shed fiber or leave an oil residue on the surface, so you get a clean finish — useful on machinery, floors, and work surfaces.

What's the difference between universal and oil-only pads?

Universal pads absorb both oil- and water-based liquids, which suits indoor shop spills with coolant and water in play. Oil-only pads repel water and float, for oil spills on water or outdoors. Match the pad to whether water should be soaked up or shed.

What are they used for?

General-purpose absorbency — wiping up drips and leaks, lining machine bases and workbenches, catching overspray, and cleaning spills. They're also a common refill for bucket and drum spill kits.

Do they work on acids or aggressive chemicals?

No. Universal pads absorb common non-aggressive liquids and don't neutralize acids or bases. For aggressive chemicals, use a HazMat or neutralizing kit and verify compatibility against the chemical's safety data sheet.

Why are they dark gray?

The dark-gray color hides absorbed grime and oil for a cleaner look and longer service life on the floor, so a partially used mat still looks tidy in a work area.

How do I dispose of used pads?

Used pads carry the hazard of whatever they soaked up, so dispose of them per your local, state, and federal waste rules. Oil-soaked pads may be recycled for fuels blending or incinerated where permitted.
