ACRYLITE® 249 acrylic sheet meets and is qualified to AECMA 4365 and MIL-PRF-8184 (Type I, Class 2).
ACRYLITE® 249 is a cross-linked cast acrylic sheet with increased resistance to crazing and solvent attack, as well as improved dimensional stability after heating.
ACRYLITE® 249 sheet is used in a wide variety of commercial, military and rotary wing transparencies in monolithic or laminated form.
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 aviation AECMA 4365 and listed on QPL for 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 Type I, Class 2 material, Class 2 material is acceptable for Class 1 applications
