Product Application
Industrial Grade
It is produced by the isomerization reaction of maleic anhydride aqueous solution recovered from the waste gas of the fumaric anhydride plant. The content exceeds 98.5%.
It is primarily used in the production of unsaturated polyester resin and alkyd resin. It is also used in the manufacture of electrophoretic paint, oil additives, adhesives, various preservatives, and other fine chemicals.
Feed Grade
With a content of more than 99.5%, it is mainly used to produce feed acidifiers and compound feed acidifiers. It can replace antibiotics, reduce the pH value in livestock intestines, promote the growth and reproduction of beneficial bacteria, and improve feed palatability and utilization.
Food Grade
It is produced by the pure benzene oxidation method. The color of the product reaches 15, the content is greater than 99.5%, and it is a white crystalline powder.
It is widely used as a sour agent, preservative, antioxidant, etc., and is mainly used as an additive in alcoholic beverages, soft drinks, baked goods, and non-staple food processing. Food-grade fumaric acid is a pure-tasting sour agent used in the production of soda drinks, juices, ice cream, and fruit candies. It also has a good anti-mold effect on white bread, vegetables, fruits, fresh meat, and other foods.
