Processing
Pre Drying
Necessary low maximum residual moisture content: 0.15%
 
Drying is not normally required. If material has come in contact with moisture through improper storage or handling or through regrind use, drying may be necessary to prevent splay and odor problems.
 
The product can then be stored in standard conditions until processed.
 
Drying time (h):3 - 4
Drying temperature (℃):120 - 140
