Can Lexan be heated and bent?
It is an amorphous thermoplastic with a continuous use temperature range of up to 265° F (129° C). If you have questions about bending Lexan, look no further. Lexan Sheet can be cold bent and can bend to tighter curves than polymethyl methacrylate, Acrylic.
What temperature does Lexan melt at?
What are the Properties of Polycarbonate?

Can you bend Lexan with a torch?
The key is to do it slowly and gently. You have a very small temperature range between the glass temperature and bubbling. I bubbled the hell out of my first piece too. I found it was easiest for me to take a propane torch, and run it back and forth over the area I wanted to bend, taking care to heat both sides.
At what temp does Lexan melt?
What temperature does Lexan form at?
Pre-heating of the clamping frame to 120°C-130°C is recommended. Since Lexan polycarbonate sheet cools rapidly, it is essential that final control and heating is carried out on the forming machine itself. Normal sheet temperatures are in the range of 170°C-225°C for mechanical and vacuum forming.
How do you bend a Lexan sheet at home?
- Peel off the plastic from both sides of the Lexan. Set the piece of Lexan on a flat table and mark the desired bend location with the black marker.
- Position a heat gun above the Lexan about 2-3 inches from the surface.
- Bend the Lexan to the proper form when it begins to sag over the edge of the table.
Can you heat Bend polycarbonate?
Polycarbonate is a thermoplastic, which means that the material becomes soft when heated. Hot bending of Lexan polycarbonate can be done in several ways: with a professional bending device, a filament or heating element, a hairdryer, an adjustable paint burner, or a convection oven.
How do you cut a curve in Lexan?
If you need to cut Lexan on a curve, use a jigsaw or band saw. Either of one these should be fitted with a blade designed to cut metal, and its teeth should be spaced anywhere from 2 mm to 4 mm apart.
At what temperature does polycarbonate soften?
Temperature behavior Polycarbonate maintains its properties over a wide range of temperatures, from -20 to 140°C. Its glass transition temperature is around 147°C, and it softens gradually above this point and flows above about 155°C.
Can you bend polycarbonate with a heat gun?
Tips for bending polycarbonate with a heat gun (adjustable): Remove the protective film from both sides and heat your polycarbonate sheet. Keep the outflow opening of the heat gun at least 2 inches from the sheet. Gently move the heat gun along the line you want to fold, ensuring that you heat it evenly.

Can you score and snap Lexan?
For long straight cuts (like you might need a table saw for), my team has found that it is often easier to snap lexan then to cut it. By using a straight edge and a knife, you can score the lexan, then snap it at the edge of a table, or something else with a sharp corner.
