New raw materials ( fillers or additives) are a cyclical constant in the world of plastics appearing as a result of new regulations (REACH), new developments (natural additives, new minerals) or the search for new properties.
Most companies are not in a position to introduce these new materials or to work with them like they did with their previous materials. The result can be poor additive dispersion or degradation, as well as preliminary difficulties in handling or dosing, with the corresponding loss of time/money and poor final properties.
