Polycarbonate is the most impact-resistant clear sheet available today, and Lexan™ is the most common brand name of polycarbonate. With various grades of Lexan sheeting, the application capabilities are Virtually unbreakable, it is approximately 250 times stronger than plate glass and thirty times stronger than acrylic of equal thickness. Lexan™- sheet provides lasting protection against vandalism, burglary, and natural occurrences, such as high winds, snow loads, and hailstorms. It is unlikely to break, shatter, or chip when bombarded with thrown objects, such as rocks, bricks and bottles, nor is it likely that this material will break when hammered twisted or bent. Because of its ductility, Lexan™ glazing can be cured and cold-formed on site from flat sheet into much tighter curves than is possible with acrylic. This provides the freedom to construct curved architectural glazing during installation without the pre-forming and fabrication costs associated with glass and acrylic.

Available Lexan Brands

Emco Industrial plastics offers several grades of Lexan polycarbonate sheeting that are suitable for applications in need of flame or bullet resistance, high impact resistance, and high optical clarity.

Brand Name Grade Features
Lexan 3412 20% glass reinforced grade, flame retardancy
Lexan 3413 30% glass reinforcement, higher stiffness and flame retardancy
Lexan 3414 40% glass reinforced, flame retardancy
Lexan 500 10% glass reinforced, impact resistance and flame retardancy

Additional brands of polycarbonate sheeting offered by Emco Industrial Plastics, includes:

  • Susta® PC GF20
  • Tecanat™ GF20
  • Unicar® RG

Lexan Polycabronate Features

  • Excellent impact resistance
  • Clarity and optimal light transmittance
  • Easily machined to custom specifications
  • Flame Retardant
  • Excellent ductility
  • Cut-to-Size

Lexan™ sheet is a superior insulating material when compared to equivalent thicknesses of glass. Double-glazing or over-glazing on existing windows can offer significant energy cost savings. clear Lexan™ sheet transmits up to 88% of visible light, close to that of glass. In applications requiring reduced light transmittance and increased shading, standard Lexan™ sheet is available in solar gray and bronze tints. Privacy patterns are also available for increased visual security.
