Montan wax

Montan wax (CAS 8002-53-7), also known as lignite wax, is a hard, high-melting mineral wax extracted from lignite coal. It functions as a lubricant and release agent across coatings, plastics processing, and industrial formulations.

OP wax is a refined, partially saponified derivative that buyers frequently specify as a distinct commercial grade. In plastics compounding, it acts as an internal and external lubricant during PVC and engineering thermoplastic processing.

This material is essential for reducing die buildup and improving surface finish on extruded profiles. Coatings formulators incorporate it into floor polishes, car care products, and industrial coatings to build slip resistance.

In adhesives and sealants, it controls rheology and prevents blocking in hot-melt systems. Metalworking applications use it as a component in drawing compounds and stamping lubricants where high-temperature performance is required.

Montan wax is supplied as hard flakes or pastilles, with refined and partially saponified grades available to meet different polarity and compatibility requirements. This versatility makes it a staple in chemical manufacturing.

Technical grade is the standard market offering, with purity and acid value specifications varying by grade and supplier. Bulk and bagged formats are typical for industrial volumes to ensure efficient logistics.
