ACRYLITE® Stretched acrylic sheet meets and is certified to AECMA 4366 and MIL-P-25690.
ACRYLITE® Stretched is a advanced ACRYLITE® 249 cross-linked material. The stretched acrylic increases the resistance to crazing and solvent attack, as well as improves mechanical behavior.

ACRYLITE® Stretched is used in a wide variety of commercial, military and rotary wing applications in monolithic or laminated form.

Most fabrication techniques used with conventional acrylic sheet materials can also be followed when fabricating ACRYLITE® Stretched sheet. Forming of stretched acrylic sheet requires unique and more sophisticated processing parameters. Forming temperatures should not exceed 230°F and forming times are much longer than with unstretched acrylic.
