Cutting petg with TS

[Tayler_mann]

Has anyone ever tried cutting PETG with their track saw. I have a stack of .040 4' x 8' sheets I have to cut into 18" x 32" pieces. I was wandering if anyone had ever tried lexan or any other plastics that compare. The cut wuality doesn't have to be perfect it is just to size the sheets to fit into my laser bed. As long as it doesn't melt it or chip it horribly it will be fine.

I cut all sorts of plastics regularly, acrylics, polycarbonates, and ABS mostly.  Most of this work is for commercial food use in cases and super markets.  I use an AGE plastics blades that I buy from Toolstoday.  They make perfect cuts.  I'm sure that Festool's plastic blade works well also but I use Amana, AGE, and industrial Freud for all my cutting blades in my various table saws, chop saws and routers.

Not quite the same, but I just cut some small Lexan rectangles with my Carvex for interior box panels.  Cut quality was great with the HS 75/2.5 bi blade -- and because the panel was inset within dados, the edge didn't have to be 100% straight, and so the jigsaw was more than sufficient to get the rough size needed (+/-1/16)

I do it all the time.  I bought the plastics blade.  I've used the regular blade too.  Virtually no difference.  Clean the blade after.  OH!!  slow the saw down to 3 it melts on higher speeds.

Definitely need to slow blade speed when cutting plastics to get good results.  It doesn't sound like your application will require perfect edges.  I usually scrape with a plastics scraper that has one long edge on one side and a small and large v and a radius, but it is easy to use a knife edge also.
