Used as a compatibilizer in polymer blends, especially in rubber and plastic mixtures, to improve interfacial adhesion and mechanical properties. Enhances the performance of thermoplastic elastomers by promoting better dispersion of fillers and reinforcing agents. Applied in adhesives and coatings to increase tack, adhesion, and durability on difficult substrates. Also utilized in impact modifiers for rigid polymers, improving toughness without sacrificing processability. Common in automotive, packaging, and industrial applications where enhanced polymer compatibility and performance are required.
