Easy-to-process polyimide resin for high temperature applications

  • Polyimide with softening temperature from 330°C to 420°C (via post-curing)
  • Main process: Resin Transfer Molding (RTM)
  • Application: aerospace & metal replacement with high-temperature requirements

Nexam Chemical has introduced an ”easy to process” polyimide resin for use in high temperature applications which features a softening temperature of above 400° C. The Neximid MHT-R resin is primarily intended for use in Resin Transfer Molding (RTM) of high temperature composite parts for the aerospace industry and industries where parts are replaced by metal and exposed to high temperatures.

Neximid MHT-R is a polyimide resin which is based on the company’s crosslinkers Neximid 100 (PEPA) and Neximid 400 (EBPA) in combination with other high temperature resistant monomers. The resin has a high softening temperature (Tg) from 330°C and up to 420°C via post-curing which is higher than most other materials and polyimides available in the market. Low melt viscosity at processing temperatures allows easy processing of the material and makes it suitable for the manufacturing of high-temperature composites using RTM technology.
