Stop the video at 3 minutes and 52 seconds to see the blade. It is an ordinary blade used to cut wood. The important thing is to install the blade in the reverse position (with the side with no writing on the blade facing out) with the pointy part of the teeth facing back at the bottom of the blade. I did not test blades with lots of fine teeth in the reverse position. However, lots of teeth would likely cause more friction (causing heat) around the cut. But without test, I do not know that for sure. The Irony is that traditionally, blades with lots of small teeth (installed in the normal position) have been used to cut plastic. I believe that the gap between the large teeth cools off the area of the cut. The most important thing in cutting with circular saws is to use sharp blades irrelevant on how you install the blades (normal VS reversed). You should try it with any sharp circular blade that you have for a test cut. Try it you'll like it!
Thanks for the electrical tape tip. I hadn't thought of that.
You're welcome!

What kind of blade is used?
