No, Lexan is an incredibly strong and durable material that is highly resistant to cracking. Developed by General Electric in the 1960s, Lexan is an incredibly strong type of polycarbonate that is nearly unbreakable and has the highest impact strength of any thermoplastic.
It has excellent heat, chemical, and UV resistance, and can even withstand temperatures of up to 300°F.
Most of the science behind why Lexan is so strong has to do with the way it is made. Polycarbonate is formed of long structural chains, rather than shorter chain branching, making it extraordinarily strong at a molecular level.
This lends a rigidity to the material that other plastics simply don’t have, and allows it to be used in applications where other plastics might easily break or crack.
Not only is Lexan remarkably strong, but it is also lightweight and incredibly flexible. Those characteristics make it an ideal material for many applications, from security glazing, to making bulletproof panels, and even aircraft windows.
Is Lexan cheaper than Plexiglass?
The cost of Lexan vs. Plexiglass will depend on the size, thickness, and quality of the product. Generally speaking, Lexan is a more expensive material than Plexiglass; however, the cost difference will depend on how much of the material is needed.
The cost of Lexan also varies depending on the grade and grade-specific requirements required. For example, industrial uses often require higher grade Lexan which will be more expensive than its retail grade counterparts.
Additionally, Lexan costs more to manufacture than Plexiglass since it requires higher temperature and pressure to be formed into the desired shape.
Overall, while the cost of Lexan is typically more than Plexiglass, the quality and durability of Lexan tends to make it worth the cost. Lexan is an extremely strong and impact-resistant material, making it a great option for projects that require durable and long-lasting applications.
It’s also considerably lighter than Plexiglass, which can make transport and installation simpler.
Which is more scratch resistant Plexiglass or Lexan?
The answer to which is more scratch resistant, Plexiglass or Lexan, depends on the application and the environment it will be used in. Plexiglass (acrylic) is more scratch resistant than polycarbonate (Lexan).
Although Lexan is a hard plastic, it scratches more easily than acrylic. However, Plexiglass is not as durable as Lexan. Lexan is a “toughened” plastic (also known as thermoplastic polycarbonate) and is much stronger than acrylic.
Plexiglass may be more scratch resistant in the short term, but Lexan will withstand the test of time, especially in outdoor applications. In addition, Lexan’s greater impact resistance makes it the better choice when safety is a concern.
For maximum scratch resistance, Lexan should be used with an anti-scratch coating, while acrylic should be used with an anti-abrasion coating.
Will Lexan yellow in the sun?
Yes, Lexan will yellow in the sun over time. This is due to the UV rays from the sun breaking down the material, eventually leading to the material becoming yellow. As Lexan is used in outdoor applications, it is important to take measures to protect the material from the sun’s UV rays in order to maintain the material’s original appearance.
This can be done by applying a UV blocking paint or coating to the material, or by using a tinted or protective film that is specially designed for Lexan surfaces.
Can Lexan be cut with a saw?
Yes, Lexan can be cut with a saw. It is recommended to use a fine-toothed saw with a slow speed, as this will minimize chipping and produce a cleaner, more precise cut. It is important to take extra precautions when cutting Lexan as it is a brittle plastic that can shatter and splinter during the cutting process.
If feasible, it is advised to use a jigsaw or circular saw with a special polymer cutting blade designed specifically for non-metallic materials. When using a handsaw, it is important to make sure that the blade is sharp to ensure a clean cut and minimize chipping.
The use of a straight edge or saw guide is recommended to ensure a straight cut. Finally, it is important to wear safety glasses to protect your eyes from broken pieces.
What is the most scratch resistant plastic?

In conclusion, the main differences between Lexan and plexiglass are transparency, weight, strength, and melting point. While both plastics have their advantages, Lexan is generally the better choice for applications where strength and UV resistance are important.
Can you drill holes in plexiglass?
Yes, you can drill holes in plexiglass. Drilling into plexiglass requires a few specific considerations and precautions. Before attempting to drill, ensure that the plexiglass is firmly fixed in place.
Use a low-speed drill, as high speed drills can heat the plexiglass, causing it to crack or shatter. Additionally, plexiglass is quite hard, so it is important to use the appropriate drill bit. High-speed steel or carbide-tipped drill bits with geometries made for plastic are recommended.
However, using a standard masonry bit is not recommended for drilling in plexiglass. Additionally, it is important to be careful to not overheat the plastic. Once the correct bit has been chosen, begin drilling at a slow speed and apply light, preferably even, pressure as you drill.
Note that it is not necessary to use lubricant as plexiglass does not chip or break easily, even during drilling. Finally, remove the resulting shavings at regular intervals while drilling. If done properly, drilling into plexiglass should be relatively straightforward and produce a clean, smooth hole.

How do you install polycarbonate car windows?
Installing polycarbonate car windows can be a difficult task if you don’t have the right tools and knowledge. To begin, you’ll need to remove the old window from the car. This can be done by removing the screws or clips that hold it in place on the door frame.
Once the window is removed, you should measure the width and length of the opening that the new window will need to fit into.
Next, you will need to cut the new window to the correct size. You can use a saw or a router with a blade specifically designed for cutting polycarbonate plastic. Make sure to use protective eyewear during this step to avoid any accidents.
Once you’ve cut the window to the correct size, you’ll need to prepare the edges. This can be done with a file or an electric sander. Make sure to sand the edges with a fine grain and to wipe away any dust particles that might remain.
Finally, you can start to fit the window into the car’s door frame. You’ll need to use a special silicone-sealer to secure the window in place on the car. After sealing the window, use a clamps to firmly hold it in place for several minutes.
Once installed, you can remove the clamps and enjoy your new polycarbonate car windows.
What polymer is used to make windshields?
Polyvinyl butyral, or PVB, is a type of polymer used to make windshields. It bonds the layers of glass together into a single unit and adds strength and rigidity to the windshield. PVB is a thermoplastic, meaning it softens when heated, which allows it to be melted and applied as an interlayer between sheets of glass.
After the cooling and hardening process, the PVB interlayer bonds the two sheets of glass together, acting as a strong and flexible adhesive. PVB is designed to absorb energy and keep the glass shards in place if the windshield is broken, thus helping further reduce the likelihood of injury in an accident.
Due to the strength and durability of PVB, windshields made with it are able to withstand high pressures and temperatures, which makes them suitable for automotive and aircraft applications.
How thick is a car window?
The thickness of a car window can vary depending on the make and model of car. Generally, the range is between 4-7 millimeters. The most common thickness is 6 millimeters and many standard car models found on the market today have windows with a thickness of 6 millimeters.
Manufacturers often opt for thinner windows as it can make the car lighter and cheaper. Most laminated glass is made up of two layers of glass with a thin layer of Polyvinyl Butyral (PVB) sandwiched in between them.
PVB adds durability and strengthens the window, allowing for a thinner glass window with enhanced safety features such as impact resistance and resistance to forced entry.
Within the car industry, safety is of utmost importance. Due to this, many car manufacturers will use a thicker window depending on the safety requirements and the passengers in the car. For example, tinted windows and high-end luxury cars will typically have a window thickness of 7 millimeters to provide maximum security and privacy.
In summary, car window thicknesses are generally between 4 – 7 millimeters, with the most common being 6 millimeters. The thickness may be modified depending on the car model, safety requirements and added features such as tinting.
What is automotive glass made of?
Automotive glass is made of a combination of two main components: glass and polyvinyl butyral (PVB). PVB is a thermoplastic material that is sandwiched between two or more glass layers and acts as a strong adhesive and sealant.
Automotive glass typically consists of two pieces of flat glass laminated together with a thin layer of PVB in the middle. This combination of materials provides strength and durability, as well as noise, UV, and thermal insulation.
The glass used in automotive glass may be either tempered or laminated glass. Tempered glass is a type of safety glass that is strengthened through a process of controlled thermal or chemical treatment.
This type of glass is stronger than normal glass and is used for the side and back windows in cars and trucks. Laminated glass is made from two pieces of glass and one layer of PVB. It is used for the windshields of cars and trucks and provides a unique form of protection from shattered glass.
What kind of glass is used in vehicles?
The most common type of glass used in vehicles is laminated glass. Laminated glass consists of two layers of glass with a layer of plastic in between. This makes it more resistant to breakage than traditional tempered glass.
It is also useful for keeping the glass from shattering if it is broken – since the plastic holds the pieces together, it is much safer in the event of an accident. Laminated glass is also better for keeping out UV rays and sound, which makes it a more effective energy-saving and noise-reducing option.
Additionally, this type of glass can be tinted to reduce glare, further making it a popular choice for vehicle windshields and windows.
What material are used in the tinted glass of cars?
Tinted glass used in cars typically consists of two primary materials: polyvinyl butyral (PVB) and ethylene-vinyl acetate (EVA). PVB is a plastic-like material that is combined with the glass during the manufacturing process.
EVA is a clear film that is applied to the exterior surface of the glass. Both of these materials work together to block harmful UV rays, reduce glare and heat, and provide privacy for vehicle occupants.
PVB is a strong and durable material that helps hold the glass together in the event of an accident. EVA is a flexible material that is applied as a liquid and cures when exposed to ultraviolet light, forming a long-lasting bond with the glass.
Together, these materials create a strong and durable tinted glass film that is resistant to scratches, cracking and UV degradation.
