Physical Properties for Lexan™ Polycarbonate 9034 Sheet

Lexan™* Polycarbonate 9034

Lexan™* 9034 uncoated polycarbonate sheet is the standard grade of Lexan™® sheet for transparent protective glazing. High-impact Lexan™® 9034 sheet may be an excellent candidate for primary glazing for economical protection against breakage or intrusion. A better insulator than glass, Lexan™® 9034 sheet may contribute to lower energy costs.
