Pre-drying recommendation:

KEBAFLEX / U must be pre-dried before processing.
Dryer type: dry air dryer
Temperature: max. 90°C
Drying time: 2 – 3 h
Moisture content < 0.02 %.

Temperature recommendation:

Melt temperature: 200 – 220°C
mold temperature: 20 – 50°C


Due to its special properties, KEBAFLEX / U may tend to stick to smooth and polished mold surfaces. Structured surfaces favor the demolding behavior. Alternatively, the mold can be provided with suitable coatings.
