Aerospace Cast Acrylic Products are ideal for aircraft cabin windows, fighter canopies, windscreens, wing-tip lenses, outer laminates and instrument panels for general aviation and military aircraft. These products meet US Military Specifications MIL-P-5425, MIL-P-8184, and MIL-P-25690 to the United States aerospace industry.
Aerospace products come in a range of sizes, thicknesses, and colors. POLY 84 (MIL-P-8184) is a uniquely formulated, crosslinked preshrunk acrylic specifically designed to provide superior craze and solvent resistance for today’s changing environment. Improvements such as lower water absorption and increased resistance to acids expands the number of “as cast” applications.
Poly 84 also meets or exceeds MIL-P-8184, Type I and II, Class 1 and 2. Its superior craze resistance makes it ideal for monolithic windscreens, outer laminates, and canopies. It is also available in transparent colors. It meets or exceeds all requirements of MIL-P-8184. Type I and II, Class 1 and 2.
