COMPONENTS FOR MELT HANDLING
For an optimal melt distribution
The components made by Maag Group guarantee intelligent
pre-heating, cooling, and diverting of the melt flow.
blendrex ® heat exchangers can be used as pre-heating devices
or as cooling devices and are also capable of tempering
high-viscosity polymer melts (up to 10,000 Pas). The
alternately twisted mixing element works most efficiently.
Polymer shut-off valves are applied in the batch process
directly under the reactor or as an emergency shutdown in
the continuous polymer process. The compact design with
short product channels and reduced volume prevents the
melt from oxidizing and ensures little rinse quantities.
The SG-V die heads ensure an even and a homogeneous
melt distribution at high and consistent throughput rates.
The flow-optimized design of the product chamber and
channels not only reduces pressure losses but also saves a
lot of energy. Short dwell-times enhance product quality.
