ACRYLITE® FOR AVIATION 249
ACRYLITE® 249 cross-linked acrylic sheet, qualified to MIL-PRF-8184 Type I, Class 2 (QPL listed) and prEN 4365, supports aircraft transparencies exposed to chemical, environmental, and mechanical stress. Developed for demanding aerospace applications, it combines optical clarity with higher resistance to crazing, solvent attack, and crack propagation.
Properties
ACRYLITE® 249 is used across commercial, military, and rotary-wing aircraft transparencies in monolithic and laminated constructions where resistance to environmental exposure and mechanical performance are required.
✔ Qualified to MIL-PRF-8184 Type I, Class 2 (QPL listed)
✔ UV transmittance <1% (290–330 nm)
✔ Cross-linked acrylic sheet developed for aerospace applications
Performance Characteristics
- Cross-linked structure supports improved resistance to crazing and environmental stress cracking
- Offers improved resistance to solvent attack in exposure to aviation fluids and cleaning agents
- Supports improved dimensional stability after heating for consistent thermoforming results
- Helps improve resistance to crack initiation and propagation under cyclic loading conditions
- Well-suited for stretching processes in high-performance transparency applications
