Montan wax, also known as lignite wax or OP wax, is a hard wax obtained by solvent extraction of certain types of lignite or brown coal.
Commercially viable deposits exist in only a few locations, including Amsdorf, Germany, and in the Ione Basin near Ione, California.
High-graded lignite wax are also found in Yunnan and Jilin, China.
Properties
Its color ranges from dark brown to light yellow when crude, or white when refined.
Its composition is non-glyceride long-chain (C24–C30) carboxylic acid esters (62–68 weight %), free long-chain organic acids (22–26%), long-chain alcohols, ketones, and hydrocarbons (7–15%), and resins; Montan wax is in effect a fossilized plant wax.
Its melting range is 82–95 °C (180–203 °F).
Key Properties
High melting point
Excellent hardness and abrasion resistance
Good lubricating properties
High chemical resistance
Good compatibility with polymers and other materials
Excellent release and surface properties
Low moisture absorption
Applications
Montan wax is commonly used in a variety of industries, including:
Key Properties
High melting point: Melts between 82°C and 95°C.

Uses
Plastics and Polymer Processing: Used as an internal and external lubricant, processing aid, and mold-release agent.
PVC Processing: Helps improve processing performance, surface quality, and release properties.
Rubber Industry: Used as a processing additive and protective component.
Polishes: Provides hardness, gloss, and water resistance in floor, automotive, and furniture polishes.
Coatings and Inks: Improves surface properties, scratch resistance, and gloss.
Adhesives: Can be used to modify hardness, viscosity, and processing characteristics.
Candles and Specialty Products: Used to improve hardness and thermal stability.
Advantages
Montan wax offers a combination of hardness, high thermal stability, lubricity, and excellent surface properties, making Montan wax a valuable raw material for demanding industrial applications.
Depending on its grade and formulation, Montan wax can be customized or selected to meet specific processing and performance requirements.
Uses
Montan wax is used for making car and shoe polishes, paints, and phonograph records, musical instrument polish and as lubricant for moulding paper and plastics.
About a third of total world production is used in car polish.
Formerly, its main use was making carbon paper.
Unrefined montan wax contains asphalt and resins, which can be removed by refining.
Montan wax in polishes improves scuff resistance, increases water repellence, and imparts high gloss.
Uses
Electric cable insulators; in polishes instead of carnauba wax; manufacture of candles, waterproof paints and varnishes.
Common Uses
Polishes: Used in shoe polish and floor wax.
Lubricants: Acts as a release agent in plastic manufacturing.
Substitutes: Replaces expensive carnauba wax or beeswax.
