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 NEXAMITE® B02 (PMDA) a monomer suitable for polyimid synthesis.
