Nexam Chemical (Lund, Sweden) has introduced NEXIMID MHT-R, a new easy-to-process polyimide resin for use in high-temperature applications, with a Tg of more than 400°C. The resin is primarily intended for use in resin transfer molding (RTM) of high-temperature composite parts for the aerospace industry. Nexam says other applications, such as machine manufacturing industry and different transport sectors, will also benefit from this material where metal replacement of parts exposed for high temperatures are possible. NEXIMID MHT-R is based on Nexam Chemical’s crosslinkers NEXIMID 100 (PEPA) and the its NEXIMID 400 (EBPA) in combination with other high-temperature resistant monomers. Features of this polyimide include a high Tg from 330°C and up to 420°C via post-curing, and very low melt viscosity at processing temperatures.
