I found a thread where moderator Dave Anderson recommended this product for bonding with UHMW.

I'm building a chip separator and am lining it with 1/8" UHMW sheet. I've had good luck adhering UHMW to jigs and fences with either double-sided turner's tape or - even better for a permanent bond - carpet tape. However this application will have the sheet effectively inside a box and not easily accessible for replacement or repair, so I'm looking for something specific to the task.

The edges of the 8" wide sheet will be adhered to the edges of 1/2" MDF, and there will be 3/4" MDF strips across the width, and the long length will be shaped into a cylinder on this substrate. The 3M 9472LE PSA looks to be a good choice for this application, but I can't find anyplace that sells this stuff in single rolls. At about $25 per roll, I'd really rather not have to buy two.

Has anyone found a source for single rolls of this stuff?

Thanks.
