At a glance
Adding a mineral filler changes the formulation balance, not just the material cost. Its effect needs to be evaluated against the intended function and the rest of the recipe.
Key points
- Particle characteristics, dispersion and compatibility can influence a trial outcome.
- Compare candidates on a consistent basis and report mass per finished component as well as material test results.
- Specify the finished-product requirements rather than endorsing a filler solely by its name.
Technical context #
Particle characteristics, dispersion and compatibility can influence a trial outcome. An increase in one measured property may come with changes in mass, processing or another performance requirement. The phrase reinforced with minerals is therefore incomplete technical evidence.
What to measure and document #
Compare candidates on a consistent basis and report mass per finished component as well as material test results. Check surface quality and relevant mechanical responses after suitable conditioning. Distinguish a solid filler from accidental inorganic contamination.
Implications for development and specification #
Specify the finished-product requirements rather than endorsing a filler solely by its name. A heavier board is not automatically stronger or better quality. Buyers should be able to connect the supplied profile to the evidence supporting its claimed performance.
