Processing
Pre Drying
CELSTRAN PBT should in principle be predried. Because of the necessary low maximum residual moisture content the use of dry air dryers is recommended. The dew point should be =< -30℃. The time between drying and processing should be as short as possible
 
Drying time (h):2 - 4
Drying temperature (℃):120 - 140
