No melt plastic cutting saw blades are designed with a negative hook angle, which greatly reduces the tendency of chip-welding or melting of acrylic sheets, Plexiglas , Lexan , corrugated polypropolyene, HDPE, polycarbonates and other plastics.
Sheet acrylic plastic is a versatile, glasslike construction material that can be cut or shaped for a wide variety of items. Straight cuts of acrylic sheet can be made on an ordinary circular
Corrugated roofing sheets are an inexpensive way to cover a patio, shed or greenhouse and are available in colors such as white, blue and green as well as opaque colors and clear plastic.
Amanas triple-chip grind, carbide-tipped teeth produce less heat than a standard blade, leaving a crisp, smooth edge without chip-welding melting of the plastic . These industrial-quality blades work great on acrylic, Plexiglas , polycarbonate, Lexan , and many other sheet plastics.
Use circular saw to cut thicker polycarbonate sheets. 1 Use fine tooth saw blade on a circular saw to cut plastic that is more than 0.125 inches 0.3175 cm but less than 0.50 inches 1.27 cm thick.

I have a lot of 2" PVC to cut. Using the big PVC manual cutting tool with a blade is a lot of work and the cuts are never flat. I need the cuts to be pretty precise because the pipes are for replacing a pool
You can cut corrugated plastic roofing with a circular saw and a carbide blade, but you must secure it well before cutting. The vibrations of the saw make it wobble, and the wobbling can bind the saw or force it off the cut line.
When cutting with a hand-held circular saw, clamp the sheet securely to the work surface to minimize vibration. A wood block 1 X 3 25 X 75 mm clamped on top of the sheet spreads the clamping force and can act as a guide for the saw.
A handsaw will suffice, but a circular power saw with a new carbide-tipped blade is best. After measuring and marking the PVC sheet where you will cut it, place the sheet on the sawhorses. Make the cut straight and consistent.
