   I've never cut plastic crown, but I cut Azek (PVC trim boards) a lot, and have never had any trouble using a high-tooth count carbide blade in a TS or miter saw.

   gj13,

   I haven't cut crown molding, but I cut a houseful of plastic baseboard a few years ago. The first cut on the chop saw melted the plastic. I have never completely gotten all the plastic off that blade. The only way I could get the job done was to cut as fast as possible, bringing the saw down and back up as fast as I could to prevent heating the material.

   Steel plywood blade installed backwards works in a mitre saw

   Try a high tooth count carbide blade installed backwards.

   I did this with vinyl siding on a SCMS, and it eliminated a pesky blowout at the fence.

   Having never worked with this material I have no idea whether or not you have already gotten a useable answer to your question. Breaktime would be a good place to make such an enquiry.

   Yeah, I thought about posting to Breaktime. Knots is where I tend to browse, though.Thanks for the answers, guys. Looks like I'll try it with a backwards blade next time.

   fiy that also works for aluminum soffit and flashings. not that it helps you in this situation but it may eventually.
