Overview
Exolon AR is a polycarbonate sheet with an abrasion-resistant coating on both sides: a glass-hard, abrasion-resistant coating (Taber test) is permanently bonded to the impact-resistant PC core, making the sheet particularly resistant to scratching and mechanical wear without losing polycarbonate's high light transmission (up to 88%) and impact strength.
The coating is chemical resistant and permits use where cleaning agents, disinfectants or occasional contact with solvents are expected. Thermoforming the coated sheet is not possible, as the coating would crack or delaminate - applications requiring forming should instead use the uncoated Exolon GP.
Typical applications include noise barriers, glazing in educational and healthcare facilities, correctional and psychiatric facilities, and chemical-resistant machine guards - wherever glazing is cleaned frequently or must resist deliberate damage.

Frequently Asked Questions about Exolon AR
1What is Exolon AR?+
Exolon AR is a polycarbonate sheet with an abrasion-resistant coating on both sides, offering glass-like surface hardness together with high impact strength and light transmission up to 88%.
2How does Liedtke machine Exolon AR?+
We saw, mill and drill Exolon AR like standard polycarbonate; the machined edge naturally remains uncoated. Thermoforming is not possible.
3What determines the price of an Exolon AR cut piece?+
The price depends mainly on sheet thickness, sheet size, machining effort and quantity. We are happy to provide a binding quote based on your drawing.
4When is Exolon AR not the right choice?+
If the sheet needs to be thermoformed, Exolon AR is not suitable - the uncoated Exolon GP is the right choice here. The surface coating is also not declared as food-safe.
