Nexam Chemical offers a series of crosslinking end-cappers and monomers with different curing temperatures to be used in the formulation of reactive oligomers/polymers. By introducing crosslinking points in the polymer backbone it is possible for example to increase the Tg, improve chemical and heat resistance as well as mechanical properties to enable more demanding applications.
Additionally to the crosslinkers Nexam Chemical offers monomers suitable for polymer synthesis, two high-purity di-anhydrides: NEXIMID® 800 (6-FDA) and NEXAMITE® B02 (PMDA) and NEXIMID® 700 a formulation of trans-1,4-cyclohexyl diammonium acetate, is offered to address the difficult incorporation of cycloaliphatic trans-1,4-cyclohexanediamine into polyimide formulations.
