POLYCAST CELL CAST ACRYLIC Solutions for Aerospace

POLYCAST CELL CAST ACRYLIC Solutions for Aerospace

Delivering aircraft transparencies for the demanding aerospace industry. cast cell cast acrylic has been manufactured and trusted by the aerospace industry for over 3 years. We offer different formulations designed to address the specific performance needs of various aircraft transparencies. That includes optical clarity and sheet cleanliness, unrivaled in the industry. We consistently surpass stringent industry standards and demands, including the strict quality levels required by Military Material Specifications. Today, in supplying the cast brand of materials, we are the principal supplier to the United States aerospace industry of acrylic sheet meeting U.S. Military Material Specifications Mil-PRF-5425, Mil-PRF-8184, and Mil-PRF-2569. A comprehensive and experienced team of One material engineers, technicians and sales & service representatives is available to help you determine the best cast acrylic solution for your needs. OUR AEROSPACE SOLUTIONS POLY A is our standard unshrunk acrylic. It is manufactured to a visual and optical aircraft specification (ASTM D-482) and is available in clear as well as transparent colors. Common applications are non-critical glazing for commercial helicopters and sport planes. POLY 9 is a semi-crosslinked material formulated to meet British specifications DTD-55. POLY II is our heat-resistant, preshrunk, clear and colored acrylic sheet formulated to meet military specification Mil-PRF-5425. We are qualified to furnish sheets in thicknesses.6" 1." to meet this specification. POLY 76 is a crosslinked, preshrunk acrylic with excellent resistance to crazing, solvent attacks and thermal dimensional change. As one of the few materials approved by the U.S. Military for use as stretched panels -2569), 76 has numerous sophisticated applications for both military and commercial aircraft. It is also available in transparent colors. 76 meets or exceeds all requirements of Mil-PRF-8184, Type I and II and Class 1. POLY 84 is a uniquely formulated, crosslinked, preshrunk acrylic. With lower water absorption, it is specifically designed to provide superior craze and solvent resistance for today s changing environment. 84 also meets or exceeds Mil-PRF-8184, Type I and II, Class 1 and 2. It is ideal for monolithic windscreens, outer laminates and canopies. Also available in transparent colors. POLY 2 is a military specification covering stretched acrylic sheet specially designed from Mil-PRF-8184 base material. It offers enhanced craze properties and increased crack resistance. It meets or exceeds all requirements of Mil-PRF-2569. POLYCAST UV-SC is a custom cell cast acrylic sheet that blocks out significant amounts of near-infrared radiation while maintaining high visible light transmission. This acrylic solution offers full UV protection for pilots and aircraft interiors without sacrificing acrylic s superior light transmission qualities. It is available in a wide range of colors and/or light transmissions, including night vision compatibility.
