Polycarbonate Sheet

​

Polycarbonate Sheet, the epitome of ultra-tough, clear glazing materials, finds versatile applications in machine guards, anti-vandal glazing, and riot shields.

 

Strength and Durability

While not totally unbreakable, Polycarbonate Sheet is approximately 250 times stronger than glass, making it one of the toughest materials available.

​

Brand Names and Grades

Also known as Lexan, Paltough, or Makralon, Polycarbonate Sheet offers various grades tailored to different applications.

​

Marguard Grade

Marguard, the scratch-resistant grade of Lexan Polycarbonate, is ideal for race car applications. Its hard coating allows easy cleaning and reduces scratches, extending window life.

​

Notch Sensitivity and Thermal Expansion

Polycarbonate Sheet is notch sensitive; drilling or notching reduces its impact resistance in those areas. Thermal expansion should be considered in applications where temperature changes are expected.

​

UV Resistance

Some grades of Polycarbonate Sheet offer improved UV resistance for external applications, while non-UV grades are suitable for internal use like machine guards.

​

Chemical Sensitivity

Standard Polycarbonate Sheet is sensitive to chemicals and acids. Cleaning with mild solutions and avoiding dry dusters or cloths is advised, particularly for Lexan Marguard grade.

​

Flexibility and Curvature

Polycarbonate Sheet can be bent along a curve within reason, while Lexan Marguard grade's hard coating provides an advantage in this aspect.

 

Specialist Fabrication of Polycarbonate Sheet

 

Pre-bent or curved Polycarbonate sheets typically require specialised fabricators due to their complexity and potential impact on the coating's flexibility.
