Bisphenol A (or BPA) is a white, solid chemical made in prilled form for ease of handling and processing. BPA has a structure which makes it suitable as a monomer to produce epoxy, polycarbonate, phenolic, polyester, and other resins. It also functions as a chemical intermediate since it can be readily halogenated, hydrogenated and sulfonated. Its halogenated derivatives are used in the production of fire retardant plastics.
An acid derived from maleic acid commonly referred to as an acidulent due to its primary use as a food additive. It is mainly used in baking powder and beverages and can replace citric acid or tartaric acid to add sourness. Fumaric Acid is also used in the production of polyester resins and dyes.
MA (maleic anhydride) is an important raw material for alkyd resin and unsaturated polyester resin (UPR), which are widely used in yachts, bathroom fixtures, automobiles, tanks, pipes and so on. MA is also used for production of 1,4-butanediol, synthetic fibers, detergents, pharmaceuticals, fuel additives and stabilizers, and other fine chemicals. In addition, it is widely applied in the preparation of certain agricultural chemicals.
