DSM Xplore developed
a twin screw compounder with a capacity of just a few grams
of material. This microcompounder is a unique asset for the development of new
material compounds.
A full-pledged material processing machine
on a laboratory bench or in a fume cupboard! The microcompounder
can process batch-volumes up to 15 ml. As an option our compounder
houses the unique Vari-BatchTM concept, which
gives you the opportunity to select your batch-volume, via
multiple recirculation channels, from 3 ml, 7 ml up to 15
ml. In the past, testing and evaluating of new materials
or formulations was not possible due to lack of sufficient
synthesized material or too expensive additives. Our microcompounder
offers a solutions to these issues. Even more, when it is
used in combination with our laboratory injection molding
machine.
The core of this laboratory compounder is formed
by a divisible fluid tight mixing compartment containing
two detachable, conical mixing screws. Both the screws and
the housing are specially treated to minimise wear and to
make them resistant against chemicals. Chemical resistance
and hardness of the barrel is essential to maintain it’s
original geometry which enables to generate reproducible
data over the years.
The main drive is continually digitally
variable and allows for axial force measurement which controls
constant die pressure for film and fiber applications, hence
through-put control. The processing temperature can be controlled
in 6 separate heating zones which enable to process with
a temperature gradient or directly via an additional melt-thermocouple.
Residence time can be varied via recirculation of the melt.
Mixing and dispersion are superb preventing agglomeration;
shear can be set by RPM or axial force control. In addition
screw flank barrel gap is also adjustable. Other standard
features are air and water cooling, N2 purge, integrated
touch screen control, axial force measurement (determination
of viscosity).
Dedicated software enables you to control
the instrument parameters and to acquire data to analyse
a processing cycle/run.
