Primary Applications of Maleic Anhydride (MA)
Maleic Anhydride's unique reactivity, characterized by its unsaturated five-membered ring structure, drives its extensive utility in various industries:
Unsaturated Polyester Resins (UPR):
This is the largest application for Maleic Anhydride. UPRs are widely used in fiberglass reinforced plastics for construction (e.g., bathtubs, pipes), automotive parts, marine applications (boats), and other composite materials, providing strength and durability.
1,4-Butanediol (BDO) and Derivatives:
Maleic Anhydride is a key raw material for the production of 1,4-Butanediol (BDO) via hydrogenation. BDO itself is a crucial intermediate for engineering plastics (like PBT, PU), tetrahydrofuran (THF), and gamma-butyrolactone (GBL).
Lubricant Additives:
Derivatives of Maleic Anhydride, particularly maleated polyolefins, are used as dispersants and viscosity index improvers in lubricating oils and fuels, enhancing their performance in engines and machinery.
Agrochemicals & Pesticides:
MA is an intermediate in the synthesis of various agrochemicals, including certain herbicides, insecticides, and plant growth regulators, contributing to agricultural productivity and crop protection.
Food Additives & Flavor Enhancers:
Although Maleic Anhydride itself is not a food additive, it is used to produce fumaric acid and maleic acid, which are widely employed as acidulants and flavor enhancers in the food and beverage industry.
Specialty Resins & Copolymers:
It's used in the production of various other resins and copolymers, including alkyd resins, which are used in paints and coatings, and maleic anhydride copolymers, which find applications as dispersants, thickeners, and sizing agents.
