Processing
Recommended processing and drying conditions
To ensure trouble-free processing and avoid any loss of quality, we recommend drying to a moisture content of ≤ 0.05%. Depending on the hardness, the recommended drying temperatures are between 80 and 110°C, with drying times of 1 to 3 hours. Better drying can be achieved in a shorter time with dry-air dryers.
It is essential to ensure that added additives also maintain a residual moisture content of ≤ 0.05%. For optimal processing results, it is advisable to dry these additives as well.
