Description

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.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
