ACRYLITE® GMU sheet is a cell cast acrylic sheet designed for general aviation and helicopter window applications and is superior to standard cell cast acrylics in both optical quality and 
thickness tolerance. It is manufactured and certified to meet the requirements of AMS-LP-391, Item A, Type I, Grade C.

ACRYLITE® GMU sheet is used for aviation applications where military specifications are not required at an economical cost.

Fabrication techniques used on standard cell cast acrylic sheet will be appropriate for ACRYLITE® GMU sheet. When drape forming this sheet, excellent results can be achieved if the sheet is heated evenly between 302 °F and 320 °F. For pressure forming or vacuum forming operations temperature of 338 °F to 374 °F are recommended.
