RHT450 is an autoclaved phthalonitrile prepreg with a uniquely high glass transition temperature and thermal stability, designed for long-term operation at temperatures up to 300°C in an oxidizing atmosphere.
High-Temperature Prepreg RHT450 is an autoclaved phthalonitrile prepreg with a high glass transition temperature and thermal stability, used for the production of polymer composite materials (PCM) by pressing and autoclave molding. PCMs produced from the prepreg are designed for use at high temperatures up to 300°C and retain their mechanical properties at temperatures up to 400°C. In an inert atmosphere, long-term operation at temperatures up to 450°C is possible. Carbon fiber reinforced plastics made from RHT450 prepreg exhibit low flammability: the oxygen index (OI) is > 80%. When exposed to flame, the material does not delaminate, and the coke residue yield is up to 80% of the binder weight.
