Low-Toxicity PMR PolyimideNew low-toxicity PMR system developed and designated LaRC-RP46. Exhibits better processability, toughness, and thermo-oxidative stability than does PMR-15. Polyimide inexpensive and readily processed into high-quality graphite-fiber-reinforced composite. Used as high-performance, high-temperature-resistant adhesive, molding, composite, film, and coating material where low toxicity desired characteristic. Significantly extends applications of PMR-type polyimides.
