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.
