It's interesting to note that only the peak temperature rating is higher. The continuous rating of 468MP is the same as the tape you specified. I was confused initially, as you mentioned using VHB tape, which is an acrylic foam core, which you probably wouldn't want to use for this application.
One thing to note, is in my case, I still use bulldog clips to hold the glass/Ultem onto the heater, so I do have constant clamp pressure acting on it. I have a bunch of bubbles in my glue layer, but they have completely gone away under the clip areas. There is also another area where the bubbles were eliminated in an area where an ABS print sat for 14 hours. I keep wondering if I could get rid of all of the air if I heated the bed up and could apply even clamp pressure?
