Are you trying to decide between Plexiglass or Lexan? If so, then you may need a bit of help. The two materials have a variety of similarities. They’re often used for similar applications in industries such as automotive and aerospace. 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
When comparing Plexiglass also known as Perspex and made of acrylic) vs. Lexan, you first need to consider what each of the plastic 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.
There are many differences between Plexiglass and Lexan. But each material can work well for the same projects. Again, it all comes down to what you expect and what you want when deciding between Plexiglass vs. Lexan. You should know that both materials are stronger than traditional glass. As a result, they’re more durable, offer more protection, and are a great fit if you’re introducing a new product that needs to be able to withstand pressure, high and low temperatures, and chemical damage.
Comparing Appearances
At the onset, it’s hard to decide between Plexiglass and Lexan based on their appearance. That’s because they both resemble glass in terms of their clarity and transparency. However, over time, sheets of Lexan are more likely to yellow and lose some of their clear quality.
When weighing Plexiglass vs. Lexan, it’s worth considering that Plexiglass tends to maintain its clarity better than Lexan even when used outdoors or placed in inclement weather. You can also polish sheets of 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 acrylic Plexiglass (Perspex) vs. Lexan – and where you’ll find some important differences between Plexiglass and Lexan. 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. If you’re comparing Plexiglass vs. Lexan in terms of rigidity, Lexan is slightly stronger. 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 Plexiglass or Lexan.
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. This makes it a great choice if your company plans to begin selling cookware.
If you’re comparing acrylic Perspex or Plexiglass vs. polycarbonate Lexan sheets in terms of resistance to chemicals, you’ll find they’re largely similar; 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 Plexiglass and Lexan.
Temperatures
Another critical factor to consider is temperature in the Plexiglass vs. Lexan 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
When deciding between Plexiglass and Lexan, price is another factor worth considering. 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 with the most strength, Lexan could be a better material option.
