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.

Suzhou Senfeida Chemical Co., Ltd. is an environment-friendly high-tech enterprise integrating research and development, production and sales of fine chemical products. It has been working intensively on active diluents, UV curing resins, environmental solvents, organic intermediates and other types, and gradually formed three business segments of environmental chemicals, fine chemicals and new chemical materials. It is mainly used in many fields such as engineering plastics, green energy materials, printed circuit boards, semiconductors, information/communication, flat panel displays and optoelectronic industries.  

Based on the development concept of "characteristic, green and excellent", the company has developed more than 30 kinds of characteristic chemical products in six series by virtue of its technological innovation strength. Namely: environmental solvent series, special chemicals series, epoxy resin additive series.
