HYGARD containment grade sheet is a polycarbonate laminate that meets ASTM F 1915 and HP White TP 0500. Unlike glass-clad products, this all-polycarbonate laminate resists spalling and white-out after repeated high force impacts, an advantage in maintaining visibility of a threat during an attack. Incorporates TUFFAK polycarbonate sheet produced for high optical quality in security glazing laminates. Exterior surfaces have a proprietary AR hard coat that facilitates cleaning and resists marring, chemical attack, and graffiti. 

Covestro’s North American polycarbonate sheet business was acquired by Plaskolite on August 1, 2018.
