Pre-drying recommendation:
Dryer type: dry air dryer
Temperature: 80 – 90 °C
drying time: 2 – 3 h
recommended max. residual moisture: < 0,02 %.
Temperature recommendation:
Mass temperature: 190 – 220°C
mold temperature: 20 – 50°C
Injection molding processing:
KEBAFLEX / U A 75 ST B.01 can be processed on standard injection molding machines with 3-zone screw with non-return valve.
