Working with the right material is crucial for ensuring optimal quality and longevity in stamped parts. But with such a wide range of options available on the market, manufacturers often face a daunting task.
Lexan, a see-through plastic or polycarbonate known for its high durability, has gained popularity across diverse industries; for many companies, choosing this material simplifies the material selection process while allowing for great reliability in highly demanding applications.
The Benefits of Lexan
Choosing Lexan over other materials — such as acrylic, glass, or poly methyl methacrylate (PMMA) or Plexiglas — can offer many advantages. Best used in areas that require a high level of impact resistance, Lexan looks quite similar to glass but provides a much higher degree of durability and resilience, as it is a polycarbonate product. This unique material can transmit up to 90% of visible light and offers the same clarity as glass.
In addition to high durability, Lexan offers the following other features and benefits:
- A high level of impact resistance
- The ability to handle temperatures up to 240 °F
- A low level of flammability
- A resistance to acids and other chemicals
- High flexibility
Even compared to a similar product, acrylic, Lexan wins out based on its high strength. Lexan is actually 200 times stronger than untempered glass, while acrylic is only up to 8 times stronger. Plus, although acrylic is less costly, it is typically shinier than Lexan and has a higher chance of cracking. However, Lexan does scratch more easily than acrylic despite being more impact-resistant.
Common Lexan Applications
At New Process Fibre, we offer Lexan washers in many different outer diameters, inner diameters, and thicknesses. These versatile fasteners are used in a range of industries, including aerospace, automotive, construction, marine, military and defense, and plumbing.
Well-known for its use in the aerospace sector to construct lightweight, high-strength aircraft windshields, Lexan can also be found in various medical-grade instruments. And in addition to offering superior scratch resistance, it’s also much less likely to shatter than its glass counterparts, making it ideal for harsh, demanding applications.
