TenCate's TC890 high temperature polyimide prepreg system utilizes PROOF Research's Advanced Composites Division 900HT resin system. 900HT is a high-temperature, polyimide-based thermoset prepreg with service temperature capability up to 1000°F (538°C). TC890 is an excellent non MDA replacement for high temperature PMR-15 applications. The 900HT resin system is an easily processable, thermally stable, polymer exhibiting the highest glass transition temperature of commercially available structural matrices. This system displays exceptional toughness, superb dielectric properties, low toxicity and maintains mechanical integrity even after exposures in excess of 1300°F (704°C).
