Product Description

Brief introduction

Pyromellitic dianhydride (PMDA), pure products are white or slightly yellow crystals. Exposure to moist air will quickly absorb moisture from the air and hydrolyzed into Pyromellitic Acid. Dissolved in dimethyl sulfoxide, dimethylformamide, acetone other organic solvents, insoluble in ether, chloroform, and benzene. Mainly used as raw material for polyimide, and crosslinking agent for the manufacture of epoxy curing agents and the polyester resin extinction. 

Pyromellitic acid(PMA), also known as 1,2,4,5-benzenetetracarboxylicacid, white to yellowish powdery crystal, is mainly used in the synthesis of polyimide, octyl pyromellitic, etc., is the main raw material for the production of matting curing agent.
