| Applications | Pyromellitic dianhydride is used as a monomer in the preparation of polyimide polymers such as kapton; thermoplastics such as polyesters, polyethers, plasticizers, and expoxy resins. It is involved in the preparation of high performance coatings due to its mechanical, thermal and oxidative stability properties. It acts as a curing agent for epoxy resins which find application in adhesives, coatings and molding powders. As an intermediate, it plays an important role in polyimide based materials like printed circuit boards, tape automated bonding and magnetic wire insulation. |
