Acrylite® GMU General Aviation Grade Acrylic Sheet AMS-LP-391, Item A, Type I, Grade C
ACRYLITE® GMU sheet is a cell cast acrylic sheet designed and manufactured for general aviation meeting ASTM D 4802 Category 1 Finish 1 & AMS-LP-391 Item A Type 1 Grade C. ACRYLITE® GMU sheet is used when superior optics and high quality are required. It is primarily used for fixed wing and rotary aircraft transparencies where military specifications are not required. ACRYLITE® GMU sheet is available in thickness ranging from .060 up to .500 in clear, green, and grey.
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.
Properties
• UV transmittance < 1 % (UV range of 290–330 nm)
• ACRYLITE® GMU sheet is tested to high optical standards

Acrylite® 249 Aerospace Grade Cross linked Cell Cast Acrylic Sheet MIL-PRF-8184F
ACRYLITE® 249 MIL-PRF-8184 Class 2 is a cross-linked, low moisture absorbing cell cast acrylic sheet that has increased resistance to crazing and solvent attack. This combined with dimensional stability and tolerance control make it the choice in a wide variety of commercial, military and rotary wing transparencies. Most fabrication techniques used with other acrylic sheet materials can also be followed when fabricating ACRYLITE® 249 sheet. Forming techniques may vary slightly.
Properties
• UV transmittance < 1 % (UV range of 290–330 nm)
• Certified to Mil-PRF-8184
• Cross-linked acrylic sheet developed to withstand craze and weathering
• Offers higher resistance to media that cause stress cracking and a higher heat deflection temperature
• Excellent suited for stretching, which makes it possible to improve its properties even further over the unstretched state
• As MIL-PRF-8184 Class 2 material, Class 2 material is acceptable for Class 1 applications as noted in QPL

Acrylite® Stretched Certified to aviation AECMA 4366 and listed on the QPL for MIL-P-25690
ACRYLITE® 249 MIL-PRF 25690 Class 2 is a Stretched cross linked acrylic sheet. The stretching process increases the resistance to crazing from moisture or solvent attack. ACRYLITE® Stretched is used in a wide variety of commercial, military and rotary wing applications in monolithic or laminated form.
Forming of stretched acrylic sheet requires unique and more sophisticated processing parameters. Forming temperatures should not exceed 320°F and forming times are much longer than with unstretched acrylic.
Properties
• UV transmittance < 1 % (UV range of 290–330 nm)
• Certified to MIL-P-25690 Class 2 as listed on the QPL for MIL-P-25690
• Offers higher resistance to environmental conditions
• Is produced from ACRYLITE® 249 Mil-PRF-8184
• Superior optical quality as well as thickness tolerances due to grinding an polishing of the material
• MIL-P-25690 Class 2 material, it is also suitable for Class 1 applications
