The graphic shows the temperature rate - of
- rise fo 10 press cycles with a package of 5 plies of Ahlstrom BluPad HT 215
gsqm each on both top and bottom of a press opening. Pressure 300
The rate of rise shows a very similar pattern from cycle 1 to 10.
Also the rate - of - rise for a one time pressing with Kraft paper of the same
weight shows an identical pattern.
The above proves that the rate - of -
rise does not change from cycle to cycle and that BluPad HT can be used at least
10 times. It also shows that it can replace Kraft paper of the same weight
without changing the temperature pattern.
