Reduce Extruder Torque
Easy, clean release from the mold is critical to high part quality, high
productivity and scrap avoidance. It also expands design freedom: better mold
release enables complex, thin parts with long flow lines.
Extruder torque plays a key role in processing speed, throughput, equipment
stress and power consumption. Because flowability of the material is a
major factor, it is particularly challenging to reduce torque when extruding
high-viscosity materials, such as glass-filled compounds.
Dow Corning's advanced siloxane additives significantly improve
material flow in extrusion operations, leading to reduced screw torque and
lower extruder amperage. These high-performance additives migrate to the
interface between the material and the screw surface, where they decrease friction and
improve slip so the extruder does not have to work so hard.
Our silicone additive technology also improves the compatibility of organic and
inorganic materials in highly filled compounds. Better compatibility further
enhances flow properties and reduces equipment degradation caused by exposure
to harsh fillers.
