ACRYLITE™ GMS ACRYLIC SHEET

 

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.

 

FABRICATION

Any fabrication technique that is appropriate for standard cell cast acrylics will be equally appropriate for ACRYLITE GMS sheet. When drape forming ACRYLITE GMS sheet, excellent results can be achieved if the sheet is heated evenly between 300F and 320F.  For pressure forming or vacuum forming operations temperatures of 340F to 380F are recommended

 

APPLICATIONS

ACRYLITE GMS sheet is used in aerospace transparent enclosures in monolithic or laminated form.  Current applications for ACRYLITE GMS sheet include instrument panels, wingtip lenses, dust covers, helicopter bubbles and aircraft canopies.

 

PROPERTIES

The table below shows typical values for 0.250 inch thick ACRYLITE GMS sheet.  Some values will change with thickness.
