Key Applications of Dibutyl Maleate
Plasticizer for Polymers DBM is widely used as a plasticizing agent in:
Polyvinyl chloride (PVC)
Synthetic rubbers
Cellulose derivativesIt enhances flexibility, softness, and workability of polymer materials, particularly in flexible vinyl products.
Intermediate for Surfactants and Detergents DBM serves as a reactive intermediate in the synthesis of anionic surfactants, especially in detergent formulations and agricultural wetting agents.
Component in Adhesives and Sealants DBM imparts excellent film-forming and adhesion properties, making it suitable in formulations for:
Pressure-sensitive adhesives
Sealants for construction and automotive applications
Additive in Paints and Coatings Acts as a co-monomer in water-based emulsion paints and specialty coatings to improve durability, gloss, and weather resistance.
