What is the effect of maleic anhydride on plasticizers?
Plasticizers.Maleic anhydride-derived dibutyl maleate and dioctyl maleate are excellent internal plasticizers for plastics. Hexahydrophthalic anhydride and diphenyl maleate (made from MA Maleic anhydride) are high-performance external plasticizers. Food Industry.Fumaric acid (from MA Maleic anhyd...Read more -
How is maleic anhydride applied in pesticides and coatings?
In coatings, maleic anhydride serves as a film-forming component for water-based, oil-based, and synthetic resin coatings (e.g., alkyd, polyester, maleic anhydride-modified rosin, and tung oil-maleic acid resins). Pesticides.Malathion (synthesized from maleic anhydride and P205) is a low-toxicity...Read more -
What is the application of maleic anhydride in Synthetic Resins?
Synthetic Resins Maleic anhydride reacts with polyols (followed by cross-linking with styrene) to form unsaturated polyester resins (UPR), a thermosetting resin. UPR is divided into fiber-reinforced plastics (FRP, commonly known as fiberglass-reinforced plastic) and non-reinforced plastics. FRP i...Read more -
