"Oil Only Sorbent Mini-Pillows are designed with a scrim that encases particulate sorbent material. Pillows are small, lightweight, and tear-resistant, and can be used in areas where more capacity is desired than can easily be achieved using a sorbent pad. Pillows are selective sorbent which will absorb Hydrocarbon-based liquids (oleophilic) and repel aqueous-based liquids (hydrophobic). Size 7 in. x 15 in. 16 pillows per case"
