Abstract
Method and composition for selectively removing liquid hydrocarbon from floors and other hard surfaces comprising granular polyisocyanurate foam. The composition desirably includes a particulate material having a bulk density greater than the polyisocyanurate foam for increasing the overall bulk density of the composition and imparting slip resistance to the floor or hard surface. Suitable particulate material includes angular sand and comminuted cellular glass. The granular polyisocyanurate foam and particulate material can be supplied from scrap material to reduce cost and landfill waste.

Composition for removing liquid hydrocarbon from floors and other hard surfaces comprising:
- absorbent granular polyisocyanurate foam having a first bulk density for absorbing the liquid hydrocarbon;
- and
- a particulate abrasive material having a second bulk density greater than the first bulk density for imparting slip-resistance to the floor or hard surface, wherein the granular polyisocyanurate foam and the particulate abrasive material are blended together to form a mixture.
