Overview of product features
Mechanical properties
Physical properties
Pre-drying:
Dryer type: dry air dryer
Temperature: 80°C
Drying time: 4-8 h
Moisture content during processing: < 0.02%.
Recommended basic settings:
Melt temperature: 250 – 260°C
Mold temperature: 90 – 120 °C
Injection speed: high
Back pressure: 40 – 80bar (spec.)
Machine selection:
Screw: Low compression screw with non-return valve
Nozzle: Open nozzle
Wear protection: Wear and corrosion protected according to machine manufacturer’s recommendation, suitable for processing highly filled plastics
Injection unit: Shot volume = 50-80% of maximum metering volume
Other important processing notes:
The residence time of the melt in the screw antechamber should be kept as short as possible. If this is not observed, segregation can occur due to the large difference in density between the filler and the carrier material if the downtimes are too high. The ideal here is metering time = cooling time. A medium back pressure leads to optimum homogenization. Due to the high filler content, the spraying equipment must be equipped with wear and corrosion protection.
