At a glance
Oscillatory rheology can help compare the response of wood-filled polymer melts under controlled conditions. Its interpretation depends on test amplitude, temperature, history and the selected geometry.
Key points
- A measurement should remain within the intended regime if linear-response analysis is used.
- Establish a repeatable procedure and check the relevant test range.
- Use rheological results together with production trials and finished-profile checks.
Technical context #
A measurement should remain within the intended regime if linear-response analysis is used. Material drying and preparation can affect comparability. A laboratory curve does not alone show how the mixture will behave through a production die.
What to measure and document #
Establish a repeatable procedure and check the relevant test range. Record sample preparation, time at temperature and any signs of instability. Compare controlled formulations and explain how the selected measurement relates to the processing problem.
Implications for development and specification #
Use rheological results together with production trials and finished-profile checks. A formulation that appears favourable in one test may introduce other limitations. The purpose is a defensible development decision, not a single-number ranking of all composite recipes.
