Polyimides

FDH Union sells high purity compound monomers for the production of polyimide resins: anhydrides and diamines, as well as their semi-finished combinations for the synthesis of complex formulations.

FDH Union also offers a range of crosslinkers and monomers with various curing temperatures for use in oligomer formulations. By incorporating our end groups into the polymer backbone it is possible to increase the glass transition temperature, improve chemical and thermal stability as well as mechanical properties to enable more difficult applications.
