PE-waxes

PE-waxes result through polymerisation of ethylene or through thermal degradation of high molecular weight plastics. On average they have molecular weights between 2000 and 12000. Especially recommended for emulsions are oxidized PE-waxes with melting points between 80°C and 140°C. Their main characteristics are hardness, elasticity, high gloss and excellent slip.

Paraffins

Today the base for paraffin is crude oil, which is specially treated and after fractional crystallisation can be divided up into macro crystalline paraffin and microcrystalline paraffin (micro wax).
Macro crystalline paraffins are primarily based on straight molecule chains and the molecular weight is between 350 and 450 with a melting point between 38°C and 65°C. The number of hydrocarbon atoms varies between 18 and 30. Micro waxes tend to have branched molecule chains and rings. The molecular weight is between 500 and 750 and the melting point is between 60°C and 90°C with generally 35 to 60 hydrocarbon atoms. The most important characteristics of paraffin are hydrophobicity, release, gloss and slip.

Fischer-Tropsch-waxes

The manufacturing of these also called “Hartparaffine” follows according to the process of Fischer-Tropsch. These waxes are primarily straight chain hydrocarbons with 20 to 50 hydrocarbon atoms and molecular weights between 400 and 700. Their melting points are up to maximum 100°C and Fischer-Tropsch-waxes show good hardness and polish-ability.

Montan- / ester waxes

Starting from brown coal Montan waxes are obtained through extraction. Subsequent refining produces acid waxes and ester waxes. By control of the refining process we are able to vary the properties, such as hardness and gloss, in our products. Melting points are between 70°C and 140°C.

Amide waxes

Specific amides from fatty acids provide waxy properties. Their typical melting point is around 140°C and they give excellent slip.

Natural waxes

Although small volumes in comparison to synthetic waxes, these waxes are also important for emulsions and dispersions. Chemically they are based on hydrocarbons, hydrogen and oxygen. Most important types are Carnauba wax (from plants) and Beeswax. Melting points are below 90°C. Main characteristics are hardness and polish ability.

PTFE

Poly tetra fluor ethylene, also known as Teflon™ has a melting point of approximately 330°C. The main properties are extremely good rub resistance and improvement of slip.

Micronized waxes

Micronized wax powders are produced by different production methods. Next to pure PE, PP, Amide, Montan, PTFE and Carnauba powders there is a variety of mixed powders, aimed to produce specific properties.
