MICROCOMPOUNDER

The AAPPI version of the DSM Xplore twin-screw microcompounder offers the capability to process small quantities (3 to 15 mL) of materials for testing and evaluating. The sample size is particularly attractive when utilizing expensive materials (e.g. carbon nanotubes, pharmaceuticals).

This compounder is comprised of a fluid-tight mixing compartment containing two detachable, conical mixing screws. Both the screws and the housing are treated to be resistant to chemical attack. The digitally-controlled main drive allows for torque measurements with continually variable screw speeds up to 250 RPM. The processing temperature can be adjusted by three front and rear separately-controlled heating zones. The mixing time can be carried out via recirculation of the melt.

If used with the medium scale injection molder or film/fiber extrusion options, the microcompounder is a complete system for mechanical testing of small amounts of materials on a limited budget.
