Transprent Gray "Smoked" Polycarbonate (Light Gray)

Transparent Gray Smoked Polycarbonate (light), aka lexan, is a high-quality and strong plastic sheet. It is 200 times stronger than glass and 30 times stronger than acrylic, offering superior durability against impacts and weather elements, making it perfect for both outdoor and indoor applications.

Ideal for a vast array of applications, from innovative commercial and DIY projects, these polycarbonate lexan sheets are not only impact-resistant but also lightweight, making installation a breeze. Our tinted gray polycarbonate sheets are engineered for longevity and performance to stand the test of time.

Polycarbonate can be used to make windows, storage shelves, machine guards, merchandise displays and other demanding applications. Polycarbonate can be formed and machined, including drilling holes, sawing and routing.

We carry several pre-cut sizes of transparent gray polycarbonate in both 1/8" thick and 1/4" thick sheets. We also offer custom cut-to-size and CNC routing services for those more demanding and technical projects.

Applications: windows, signage, partitions, machine guards, merchandise displays, storage shelves, automotive, aviation, security barriers, marine accessories, skylights, protective shields, face shields, robotic parts, boat windows, patio covers, hobbyist applications, and a variety of other applications.

Key Characteristics of Transparent Gray Polycarbonate:

  • High Impact Resistance: Polycarbonate sheets are almost unbreakable, with an impact resistance significantly higher than glass or acrylic.
  • Transparency: Light smoked gray tint.
  • Lightweight: Lighter than glass and easier to handle, transport, and install.
  • Durability: Maintain physical properties over a wide range of temperatures and conditions.
  • Flexibility: Polycarbonate can be easily thermoformed or cold bent into curved shapes, allowing for architectural creativity.
  • Easy to Fabricate and Install: Can be cut, drilled, and installed with standard tools, making them suitable for DIY projects.
  • UV Stabilized: UV stabilized to help mitigate effects of ultraviolet light exposure. Note this is not the sames as UV resistant.
  • Dimensional Stability: Exhibits minimal thermal expansion and contraction.

The Term lexan is commonly used to describe polycarbonate. Actual name brand will depend on current stock.
