Company
profile: Völpker – a family-owned company with innovative strength
With our more than 100 years of production history, we are among the
most long-standing wax producers in Europe and are internationally renowned as
a reliable manufacturer and supplier of montan waxes and special waxblends.
True to the motto “to make ideas work”, we do
everything to improve and optimize our customers’ products and processes. We
design special waxes that are precisely tailored to their requirements. We have
served as a reliable partner and developed individual solutions
for many branches in recent decades.
Product
information: Montan waxes – when performance counts
Montan waxes are used as high performance additives in the plastics
industry, due to their unique properties. They serve as combined external and internal lubricants,
nucleation additives and dispersing agents in many types of plastics and processing methods. Montan waxes are
particularly valued for new, technically demanding tasks when it comes to
special requirements in terms of the performance of a high performance
lubricant.
Examples of applications
Thermoplastics: PA, PBT, TPU, PC, PVC,
Styrenics
Thermosetts:
Epoxy resins, Phenolic resins, Polyurethane
The salts of montanic acid act as nucleating agents and are added to
crystallizable thermoplastics, such as polyamides. Their purpose is to
accelerate crystallization and thus speed up the production process.
Montan waxes serve as dispersing agents in masterbatches for coloring
plastics. They ensure that the pigment particles are properly wetted and give
rise to a finer dispersion (e.g. also in PS, PMMA, SAN, PC). Agglomerates are
thus prevented from forming in the polymer. In the end product, this leads to
very good color strength and distribution, provided that the wax and polymer
are of similar polarity and are highly compatible with one another.
Partially saponified montan wax esters are suitable dispersion agents
for filled polymers, e.g.: talcum filled PP, fibreglass filled PBT, PA, PC. For highly cellulose
fiber filled polymer composites, Völpker offers processing aids based on
regrowing waxes.
Long-term
availability
Planning certainty is an important factor for us and for our customers’
production processes. That is why we at Völpker pay particular attention to the
long-term availability of raw montan wax, which is extracted from bituminous
lignite. According to our raw material supplier, the global supply of raw wax
will be secure until at least 2030. At the same time new lignite deposits are
also being explored to ensure product availability beyond the year 2030.
