Compact Laminate, also known as solid phenolic, is a paper fiber-based solid surface material that is warmer to the touch than typical acrylic or polyester materials.

Definition: the compact laminate is essentially very thick HPL, up to and exceeding half-an-inch. Extra layers of phenolic resin-saturated kraft paper in the core gives it its thickness and strength, as well as its characteristic black or brown color. Some hpl manufacturers offer a wider variety of core colors.
