Opticor™ Advanced Transparency Material

PPG aerospace transparencies Opticor™

Opticor™ advanced transparency material is an innovative, high performance, optically clear, transparent plastic for the aerospace industry.  Opticor™ advanced transparency material is designed for use in all aircraft transparency applications, including cockpit windows, cabin windows, landing light lenses and wing tip lenses.

Opticor™ advanced transparency material provides excellent material performance and allows the ability to cast optimized, complex curvature transparencies. Opticor™ advanced transparency material offers lighter weight opportunities for aerospace transparency designs, having a lower specific gravity than MIL-P-25690 stretched acrylic. This product has exceptional craze resistance, no in-plane cracking, outstanding flammability resistance, greater impact and crack propagation resistance, and outstanding stress craze resistance.  Flammability testing of an Opticor™/stretched acrylic laminate was conducted per 14CFR Part 25.853 (a). In post-test inspection, the stretched acrylic showed significant burning while the Opticor™ material did not burn or char, demonstrating the unique stability of the material in flame conditions.

Additionally, Opticor™ advanced transparency material can be cast to shape in a wide range of thicknesses and shapes, allowing aircraft transparency designers to reduce aerodynamic drag and improve the aircraft aerodynamic performance.
