Polyurethane (PU) is used to produce three different types of plastics depending on how they are manufactured: thermoplastics, thermosets or elastomers.
We find these in everyday items such as clothing, cars, insulation, adhesives, potting compounds and rigid/soft foams.
The different demands of the plastic types require fillers adapted to them. Fillers based on fine, natural calcium carbonate optimally support these properties without impairing the processing of the materials in terms of their colour, surface or even grip.
Therefore, the industrial mineral must be chemically highly pure and remain stable for a long period of time after mixing into the polymer matrix so that it does not cause any ageing effects in the end product.
