Functional masterbatch dosage trials need a fixed baseline

Trial practice

A dosage ladder tells us something only when the base resin, machine settings and test method remain stable. If temperature, cycle and dosage all change in the same run, a better part cannot be traced to a specific adjustment.

We normally retain an untreated control and move through planned increments. Each step receives enough material and running time to clear the previous condition, after which the same measurements and visual checks are repeated.

Choose the dosage range from the application

Send the resin, current formulation, product weight, mixing method, production rate and target result. We use these details to set the first dosage range and to identify which secondary properties, such as stiffness, colour or surface, must be checked at every step.
