For the polymer and plastics industry
Talc has long been one of the most important fillers for adjusting the thermal and mechanical properties of plastics and is remarkable in many aspects.
When used in paints and coatings, the distribution and wetting of the pigment and filler particles with the low viscosity binder can be controlled relatively easily by increasing the mixing time and agitator speed over a wide range.
Changing the formulation by adding auxiliaries is also done much easier than in the production of plastic parts by injection molding or extrusion.
The full potential of this filler can therefore rarely utilized in the manufacturing of plastic parts. High viscosities and limited shear rates in the extruder, as well as high temperatures and limited dwell times, make it difficult to process the polymers and the functional filler talc.
In order to minimize these procedural difficulties, Nobelmin GmbH has launched a number of development and research projects.
Optimize product qualities
NOBELMIN talc is known for its nucleating effect in conventional thermoplastics such as polypropylene. Talc particles modify the polymer morphology during the crystallization phase by increasing the number and type of nuclei in the polymer melt.
Micronized MinTalc products from NOBELMIN GmbH are highly efficient nucleating and reinforcing agents and in this way increase stiffness and crystallization. This behavior is given if the lamellar structure is maintained during the micronization process.
Experts collaborate with experts
Our development projects are carried out in cooperation with universities and internationally active development partners. In this way, practical experience is supplemented by scientific investigations and methods.
As NOBELMIN GmbH, we also carry out publicly funded research projects independently or as a research partner (e.g. with the Institute of Polymer Research, a well-known partner of German industry).
Outsourcing R&D ensures that the company remains at the cutting edge of technology and has a high degree of flexibility when it comes to rapidly changing research topics. At the same time, unnecessary infrastructure costs are avoided, so that the competitive disadvantages for Nobelmin GmbH as a medium-sized company can be reduced.
In the area of marketing and product development, Nobelmin also makes use of its international network and cooperation with a globally active, renowned insider in the industrial minerals sector.
Bioplastics and future projects
The environmental awareness of the population (also due to the millions of tons of plastic waste produced annually) is constantly increasing. Now the plastics industry is looking for ways to optimize its ecological footprint by developing environmentally friendly bioplastics.
Bioplastics such as polylactic acid (PLA), cellulose, starch, polyhydroxyalkanoates (PHA) and polybutylene succinate (PBS), or blends and modifications of these polymers, are possible avenues for this desired transition in materials.
These polymers are made from renewable raw materials and, without the persistence of polymers made from petroleum (long-term environmental durability), are much more environmentally friendly due to their faster biodegradability.
Used on a large scale, bioplastics could significantly reduce carbon emissions and the carbon footprint of the chemical industry.
Our NOBELMIN in-house laboratory, fitted with the most modern equipment, permanently ensures development and production monitoring.
Our team of R&D experts aims to embrace innovative developments as technology advances and provide technical support to a global customer base. Chemists and engineers work together in various disciplines to drive new products, new processes, and new applications.
