What kind of tape should be used to seal the seams of foam board?

We are using XPS on a basement wall. I have heard of using foil tape or Tyvek tape but I have read these may not the appropriate choices. Some tapes can eat the foam or provide a permanent seal for years.

Tom,
In my experience, the best tapes for XPS are either Siga Wigluv or Siga Sicral. (These European tapes are available from Small Planet Workshop.)

The best U.S. tape for XPS is 3M All Weather flashing tape.
