Leave a message

Maleic anhydride, as a key organic chemical raw material, is widely used in many industrial fields. It is the main raw material for the production of unsaturated polyester resins, which are further used in the manufacture of coatings, glass fiber reinforced plastic, artificial marble and other products to improve the physical and chemical properties of the products. In addition, maleic anhydride is also widely used in the field of pesticides, such as the production of high-efficiency and low-toxicity pesticides- malathion, which provides a powerful means of disease and pest control for agricultural production. In the pharmaceutical industry, maleic anhydride plays an important medical value as a raw material of long-acting iodide and other drugs. At the same time, it can also be used as a plasticizer, lubricant and synthetic oil raw material, effectively improve product performance and extend service life. Maleic anhydride can also be used as a compatibilizer and toughening agent for PC/ABS alloys, as well as a raw material for coatings and inks, further broadening its application range. In addition, the production of fine chemical products such as anhydride acetate and tetrahydrofuran is also inseparable from the support of maleic anhydride, and these products are also widely used in chemical, textile and other fields. To sum up, maleic anhydride plays an important role in many industrial fields and is a key force to promote the development of related industries.
