ACRYLITE® GMS ACRYLIC SHEET
MIL-P-5425
DESCRIPTION
ACRYLITE GMS Aerospace Acrylic Sheet is manufactured to meet or exceed the requirements of military specification MIL P-5425E. ACRYLITE GMS sheet is manufactured in equipment that is reserved for aerospace acrylic products, is subjected to a preshrunk cycle, and undergoes an optical inspection which is among the most critical in the industry. When drape forming ACRYLITE GMS sheet, excellent results can be achieved if the sheet is heated evenly between 300°F and 320°F. For pressure forming or vacuum forming operations temperatures of 340°F to 380°F are recommended
