Description

2-Butenedioic Acid(Z)-, Dioctyl Ester, Polymer With Ethene And Ethenyl Acetate is a high-performance polymer additive, specifically a copolymer of maleic acid dioctyl ester, ethylene, and vinyl acetate. This compound is valued for its ability to modify the rheological and surface properties of polymer systems, enhancing processability and end-product performance. It is a critical raw material for manufacturers in the plastics, coatings, and specialty chemical industries seeking to improve flexibility, adhesion, and compatibility in their formulations.

Application

• As a plasticizer and processing aid in PVC and other thermoplastic formulations to improve flexibility and reduce melt viscosity.
• Used as a modifier in adhesive and sealant systems to enhance tack, adhesion to low-energy surfaces, and cohesion.
• Functions as a dispersing agent and compatibilizer in pigment masterbatches and filled polymer compounds.
• Employed in the formulation of specialty coatings and inks to improve film formation, gloss, and substrate wetting.
• Serves as a viscosity modifier and flow control agent in lubricant greases and industrial fluids.
• Acts as a key intermediate for the synthesis of further functionalized polymers and surfactants.
