Micro-compounders are suitable for early material development when only a few grams of sample available for testing . For example, 5 grams is sufficient with a micro-compounder.
All micro-compounder models are equipped with a back-flow channel and a bypass valve which allow control of the residence time of the sample in the compounder. Depending on the compounder model, it is also possible to measure the relative sample viscosity at different screw speeds. When combined with a mini injection molding machine, scientists can produce specimens for further analysis from limited sample amounts.
