Lexan is a polycarbonate resin thermoplastic. In a nutshell, what that means is that it's a solid substance that can deform in extreme heat (typically 147 degrees Celsius, or 297 degrees Fahrenheit) and whose molecules are comprised of repeating subunits.Similarly, is polycarbonate and Lexan the same thing?
Yes, they are the same thing. Lexan® is actually a brand name of polycarbonate manufactured by Sabic Innovative Plastic. We offer both Lexan® and Makrolon® brand polycarbonate sheet. Makrolon® is manufactured by Sheffield Plastics Inc.
Likewise, what is polycarbonate made of? Polycarbonate, or specifically polycarbonate of bisphenol A, is a clear plastic used to make shatterproof windows, lightweight eyeglass lenses, and such. General Electric makes this stuff and sells it as Lexan. Polycarbonate gets its name from the carbonate groups in its backbone chain.
Also to know, is Lexan shatterproof?
Common Lexan Polycarbonate Sheet Uses Its high clarity and ability to be produced in a wide variety of colors make it perfect for situations where you need the transparency of glass and the protection offered by acrylic's high shatter resistance.
Is Lexan the same as plexiglass?
Lexan has the higher impact resistance of the two and will (in most cases) bend rather than crack. Besides being less inclined to discoloration, Plexiglass is more scratch-resistant and tends to be the less costly, but is does not have the same strength as Lexan.
Why is lexan so expensive?
Polycarbonate (lexan) is expensive because it's nearly indestructible. Can you get by with acrylic? Numerous sources say that acrylic can't hold up to the heat.Will Lexan stop a bullet?
Lexan, by its self, is not 'bullet proof', In most cases it is a laminate of Lexan and Plexi with a soft Polymer bonding agent.Can you drill through polycarbonate?
Standard wood working drill bits are suitable for drilling holes in polycarbonate sheet. This will ensure the drilling will not blowout the panel as the drill exits the material. Do not under any circumstances use a centre punch on a polycarbonate panel, it's very likely to cause damage.How much does Lexan cost?

Will Lexan yellow in the sun?
It depends on climate and whether the Lexan was treated or coated for UV exposure. There are greenhouses that go far more than 10 years and they aren't yellow. For untreated Lexan the yellow is on the surface and can be polished off.Does Lexan scratch easily?
it averages much higher on the rockwell scale which determines how hard the material is . and since its harder than plexi it is more scratch resistant. Straight polycarbonate (Lexan) is EASIER to scratch than acrylic (Plexiglas).Can Lexan crack?
Lexan will NOT crack if you drill it. In fact you can take a piece of Lexan and bend it 90* and it will not crack or brake.Why does polycarbonate turn yellow?
The most common procedure used to protect the sheet is a microscopic layer of UV polycarbonate inhibitor. When the polycarbonate is attacked by the UV, it changes color and starts to become yellow. This phenomenon happens because the connections between the polycarbonate molecules lose their strength.Is Lexan BPA free?
The bulk of the research shows that Plastic #7 (Lexan, Nalgene, and other polycarbonates) bottles do not leach enough bisphenol A to cause health concerns in humans. After concerns were raised by consumers, most manufacturers reformulated their plastic to eliminate BPA.Will plexiglass yellow in the sun?
Acrylic (Plexiglas®, Lucite®, and Acrylite®) comes from natural gas and is completely inert when in solid form. American-made acrylic does NOT yellow in the sunlight. There are three other clear plastics that do yellow in the sun and get confused with acrylic- Styrene, PETG, and Polycarbonate.Is Lexan brittle?
Lexan is not brittle.Can you cut Lexan?
When you need to cut Lexan, you can essentially treat it as a sheet of plywood and cut it with any power saw you would use for that material. Make straight cuts with a circular saw or table saw, and curved ones with a band saw or jigsaw. You should use carbide-tipped blades with closely spaced teeth.Is Lexan flammable?
Description: Lexan™ Flame Retardant Sheet (9034V), UL-listed material for flammability, is a clear polycarbonate sheet that combines excellent formability and impact resistance.Does plexiglass block UV?
Although UV filtering plexiglass can not completely prevent colors from fading or darkening, it does filter out up to 98% of harmful UV light. The UV protection of this acrylic sheeting only blocks UV wavelengths shorter than 400 nanometers.How do you clean Lexan?
Wash Lexan Sheet with a mild soap or detergent (e.g., Joy** dishwashing liquid) and lukewarm water using a clean sponge or a soft cloth. Rinse well with clean water. Dry thoroughly with a chamois or moist cellulose sponge to prevent water spots.Does polycarbonate block UV?
Polycarbonate lens provides protection from the harmful UV rays of the Sun. Polycarbonate lenses blocks 100 percent UV. Whereas uncoated plastic sun glasses blocks about 88 percent UV. Generally cheaper sunglasses are made of Triacetate which blocks about 40 percent UV.Is polycarbonate bad for the environment?
However, due to the presence of bisphenol A, many manufacturers have stopped using polycarbonates for applications related to human intake. PC in landfills is definitely an environmental nightmare. It never biodegrades since it is made of petroleum. The chemicals leach into the environment causing significant damage.
