Are you trying to decide between Lexan or Plexiglass? If so, then you may need a bit of help. The two materials have a variety of similarities. They’re often used in the exact same applications. In the end, it comes down to your project, your needs, and your budget. Polymershapes can help explain the pros and cons of these two materials so that you can choose the material that’s best for your needs.
The Inner Workings
In choosing between Lexan or Plexiglass, you first need to consider what each of the materials is made of before making a decision. That can have an impact depending on the application or project that you’re overseeing. Companies use polycarbonate plastic to make Lexan. Plexiglass, on the other hand, is made out of acrylic.
There are many differences between lexan and plexiglass. But each material can work well for the same projects. Again, it all comes down to what you expect and what you want. You should know that both materials are stronger than traditional glass. As a result, they’re more durable and offer more protection.
Comparing Appearances
At the onset, it’s hard to decide between Lexan vs. Plexiglass based on their appearance. That’s because they both resemble glass in terms of their clarity and transparency. However, over time, Lexan is more likely to yellow and lose some of its clear quality.
Plexiglass, on the other hand, tends to maintain its clarity better than Lexan even when used outdoors or placed in inclement weather. You can also polish Lexan to bring back its clarity. Either material is ideal for outdoor applications or aesthetic purposes, such as greenhouse glass, automobile glass, and exterior signage.
Overall Strength
Strength is an essential consideration when you’re trying to pick between Lexan or Plexiglass – and where you’ll find some important differences between lexan and plexiglass. Both of them can withstand higher impacts than glass. Lexan is the strongest and can withstand impacts to such a degree that it won’t crack. Instead, it displays resistance by bending. Typically, Lexan offers a tensile strength of up to about 10,100 to 10,200 psi (pounds per square inch).
Plexiglass is still quite strong but may crack or chip, given enough time or impact. That’s because it’s a little less rigid than Lexan. Plexiglass typically offers tensile strength of up to 10,000 psi.
Resistances
While resistance to impact may be one concern, resistance to other substances can also determine which material you choose when considering Lexan vs. Plexiglass.
Plexiglass is resistant to most chemicals, including many acids and bases unless they’re heavily concentrated. Because of that, plexiglass is a great choice when you need materials that withstand detergents, oils, and fats.
Like Plexiglass, Lexan is resistant to many bases and acids at non-concentrated levels. Lexan also has good resistance to oils, greases, and fats. Additionally, this material is resistant to ethanol, isopropanol, and other forms of alcohol – marking another one of the differences between Lexan and Plexiglass.
Temperatures
Another critical factor to consider is temperature in the Lexan vs. Plexiglass debate. Some materials hold up better to extreme temperatures than others. Plexiglass has a solid temperature resistance, reaching its softening point at a temperature of around 210 degrees Fahrenheit or higher. This material typically reaches its melting point when temperatures reach or exceed 320 degrees Fahrenheit.
Lexan is slightly more temperature-resistant than plexiglass. This material reaches its softening point when temperatures reach or go above 300 degrees Fahrenheit. Lexan reaches its melting point as temperatures exceed 400 degrees Fahrenheit.
Price
In the battle of Lexan vs. Plexiglass, price is another issue. Plexiglass is generally the less expensive option, which may play a factor in your choice. If price isn’t an issue for your project, or you need something the most strength, Lexan could be a better material option.
