Fumaric acid is used in the production of unsaturated polyester resins. This type of resin is characterized by good chemical resistance and heat resistance; the copolymer of fumaric acid and vinyl acetate is a good adhesive. Copolymer with styrene is the raw material for manufacturing FRP. The plasticizer made by fumaric acid is non-toxic and can be used for vinyl acetate latex in contact with food. This product is a fine chemical intermediate such as medicine and optical bleaching agent.
