Sikorsky CH-53 Sea Stallion Helicopter

With the rigorous operating requirements of the CH-53, PPG has designed today’s transparencies using CR-39® monomer, a lightweight plastic material with durability to withstand high temperatures and high altitudes while maintaining critical optical quality. CR-39 monomer has been used for decades in eyewear.

A leading and experienced manufacturer of windshields, canopies, windows, blast barriers and specialty transparencies for military applications, PPG has a broad range of capabilities to design and produce advanced-technology transparencies that meet the demanding requirements of military air and surface operations.

PPG offers a variety of transparent structural materials tailored to aerospace applications.

Plastic substrate materials currently in production include acrylic that is strong and lightweight, and polycarbonate that has superior impact resistance and a high strength-to-weight ratio. PPG also is  developing exciting, new transparent structural materials with superior structural properties that have the potential to replace both acrylic and polycarbonate.

For example, new OPTICOR™ advanced transparency material provides unprecedented performance and unique design capabilities that meet the demanding needs of today’s aerospace industry. This innovative high-performance, proprietary PPG plastic is superior to other commonly used aerospace plastics, offering exceptional resistance to abrasion, chemicals, ultraviolet degradation and fire. Because it resists crazing, Opticor advanced transparency material maintains optical clarity. It has lower density than stretched acrylic and low moisture absorption, and it is an excellent substrate for metallic and nonmetallic coatings. Unique non-uniform shapes can be created with Opticor advanced transparency material.

PPG proprietary interlayers bond the plies together and provide ballistic properties, bird-impact resistance and pressure “fail-safe” capability.

Proprietary electrical heating systems provide anti-ice/antifog protection.
