At a glance
The best compatibiliser dose is not necessarily the highest tested dose. WPC development should identify a stable, reproducible formulation window rather than select a peak result from a small trial.
Key points
- A dosage study needs a consistent basis and controlled ingredients.
- Plan multiple levels with repeat measurements and a reference formulation.
- Select a commercially practical window that tolerates expected production variation.
Technical context #
A dosage study needs a consistent basis and controlled ingredients. If the added material changes the overall polymer proportion, that change should be included in the interpretation. Otherwise several effects may be attributed incorrectly to one additive.
What to measure and document #
Plan multiple levels with repeat measurements and a reference formulation. Observe processing, dispersion and relevant conditioned properties. Examine whether an apparent optimum is larger than normal experimental variation before drawing a conclusion.
Implications for development and specification #
Select a commercially practical window that tolerates expected production variation. Verify it on the intended process and record the boundaries. A laboratory optimum for one fibre and polymer combination should not be published as a ready-to-use formula for all WPC.
Related reading and evidence limits #
