Mil-Spec Acrylic

  • ACRYLITE® 249
Acrylite 249 acrylic sheet meets and is certified to MIL-P-8184F (Type II, 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. This specification requires optical quality cast acrylic sheet that is superior to conventional acrylic sheet. ACRYLITE® 249 sheet is used in a wide variety of aviation and ground vehicle transparencies in monolithic or laminated form.
Acrylite GMS acrylic sheet meets and is certified to MIL-P-5425E for use in the aviation industry as a laminate part or as a stand alone sheet. It has the optical quality, hardness and sheet tolerance required by the industry. It is manufactured using equipment that is reserved for aviation acrylic products and is subjected to a rigorous optical inspection, the most critical in the industry. Current applications include instrument panels, wingtip lenses, dust covers,
helicopter bubbles and aircraft canopies.
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 using the same process and the exacting optical requirements as product manufactured to meet MIL P-8184F and MIL P-5425E. ACRYLITE® GMU sheet is a good choice for meeting the difficult optical requirements of MIL P-8184F and P-5425E, but is more economical and ideal for many non-military aircraft applications.
  • POLY A
    Polycast Poly A is the standard unshrunk acrylic manufactured to a visual and optical specification. It comes in clear as well as transparent colors. Applications include non-critical glazing for commercial helicopters and sport planes.

    Polycast Poly II is the most versatile material for aircraft glazing. This methyl methacrylate polymer is preshrunk vertically or horizontally. Properties are improved resistance to weathering and aging. It meets or exceeds all requirements of MIL-PRF-5425E. Applications span the entire spectrum of the marketplace, ranging from wing-tip lenses to edge-lit panels.

  • POLY 84
    Polycast Poly 84 is a uniquely formulated, crosslinked, preshrunk acrylic specifically designed to provide superior craze and solvent resistance. Improvements such as lower water absorption and increased resistance to acids expand the number of “as cast” applications. It meets or exceeds all requirements of MIL-PRF-8184F, Type II, Class 2. Poly 84 is also available as a stretchable grade. It offers qualities of the standard Poly 84 plus the superior cleanliness and processing required to yield a high quality billet for stretching. Applications include monolithic windscreens, outer laminates and canopies.Download the Polycast Aerospace Grade Material Data Sheet.pdf

  Additional Acrylic Products

  • Bullet-Resistant Acrylic
    ​Acrylite® GP 1.25" and Polycast MP 1.25" acrylic sheets have a higher clarity than glass or polycarbonate. They have an optical clarity of 92% light transmission and only .7% haze factor and weigh 48% less than glass of the same U.L. rating. To fabricate shapes, they can be heated and formed and also drilled, machined, sawed or polished. Because they are U.L. 752 certified as level 1 bullet-resistant material, indoor and outdoor, for use against small-power arms, they have many applications. Some of those applications are teller, gasoline or cashier stations, taxicab partitions, police stations, store windows and computer installations. Level 2 and Level 3 certified bullet-resistant acrylic sheets are also available.

  • Acrylic Mirror Sheet
    Half the weight of plate, Acrylic Mirror is shatter resistant with extensive design flexibility. It can be cut straight edged or into curved shapes by sawing and can also be machined or drilled. Acrylic Mirror is highly reflective with all sheets protected on the front surface with clear film or paper masking. Acrylic Mirror comes in a wide variety of colors and is available in both extruded and cast.
  • “See-Thru” Acrylic Mirror
    “See-Thru”, sometimes called two-way mirror, is a semi-transparent film of aluminum deposited on an acrylic or polycarbonate substrate. This allows a percentage of incident light to pass through while reflecting the remainder. From the illuminated side it is a mirror and from the darkened side it becomes transparent. “See-Thru” has been used successfully in monitoring and surveillance operations in such places as stores, correctional and psychiatric institutions, hospitals, and casinos. “See-Thru” is also used to make infinity lights and multiple image devices. It can be used in advertising and for special theatrical props and effects.
