Microcrystaqlline waxes are a type of wax produced by de-oiling petrolatum, as part of the petroleum refining process. They differ from paraffin waxes in that they have poorly defined crystalline structure, darker color, and generally higher viscosity and melting points. Microcrystalline waxes are moisture free and range in color from a white to a brown, depending on the degree of refinement. Highly refined Micros are white. Microcrystalline waxes excellent for laminating, coating, or hardening materials.
