Used in automotive and industrial applications for its excellent thermal stability and mechanical strength, especially in under-the-hood components. Commonly employed in plastic parts requiring resistance to heat and chemicals, such as connectors, sensors, and housings. Acts as a compatibilizer in polymer blends to improve adhesion between dissimilar plastics. Utilized in coatings and adhesives due to its good film-forming properties and reactivity through anhydride groups. Also applied in the modification of resins and as a dispersant in various formulations.
