Microcrystallines (Micros) are amorphous-like in appearance; are flexible, have higher tensile strength and more adhesion than paraffin, are less oily, and typically have a higher melting point than paraffin. The molecular weights of commercial Micros are between 580-700 g/m, with the average molecule containing 41-50 carbon atoms. There are straight-chain molecules present, but the largest proportions of molecules are branched chain hydrocarbons. Micros are compatible in all proportions with other mineral waxes and their oils, most vegetable waxes and their oils, esters and their oils and resins.
