Categories:	Polymer; Thermoplastic; Polycarbonate (PC); Polycarbonate, Molded
Material Notes:	Lexan® 9034 uncoated polycarbonate sheet is the standard grade of LEXAN sheet for transparent protective glazing. High-impact LEXAN 9034 sheet can be utilized for primary glazing, or on either side of existing glazing for economical protection against breakage or intrusion. A better insulator than glass, LEXAN 9034 sheet contributes to lower energy costs. Information provided by Aurora Technologies.
