Product description

RS-51 is a very high temperature prepreg based upon P²SI®’s AFRPE-4 resin. It’s polyimide chemistry provides extreme thermal oxidative stability for very high temperature applications such as jet engine seals, ducts and composite structure. RS-51 is subject to ITAR controls and as such, mechanical and processing data are restricted.
