Polyethylene-graft-maleic anhydride is widely used as a compatibilizer in polymer blends and composites. It enhances the adhesion between non-polar polymers like polyethylene and polar materials such as glass fibers, fillers, or other polymers. This chemical is also employed in the production of adhesive formulations, where it improves bonding strength and durability. Additionally, it serves as a coupling agent in wood-plastic composites, ensuring better mechanical properties and moisture resistance. In coatings and paints, it acts as a modifier to enhance surface adhesion and film integrity. Its versatility makes it valuable in various industrial applications, including packaging, automotive, and construction materials.
