In polymer composites, PE-g-MAH (polyethylene-graft-maleic anhydride) provides a number of benefits as a coupling agent. PE-g-MAH greatly improves the adhesion and interfacial bonding, filler dispersion, thermal and chemical stability, and overall performance and characteristics of polymer composites. Its adaptability and application possibilities are further enhanced by its compatibility with different polymer matrices. Advances in the automotive, aerospace, construction, and packaging industries have resulted from the widespread usage of PE-g-MAH as a coupling agent in areas that need high-performance materials. Researchers and engineers can continue to create novel polymer composites with improved qualities and broaden the spectrum of applications in various industries by utilizing the advantages of PE-g-MAH.
Maleic anhydride functionalized ethylene polymers, or PE-g-MAH series products, are primarily used to alter ethylene-based matrix polymers. In order to accomplish the goal of compatibility between various polymers, it reacts effectively with polymers having -NH2, -OH, and other groups and offers an excellent coupling effect between them.
Maleic anhydride (MAH) can be grafted onto PE using a variety of techniques, the most common ones being solution, melting, solid phase, solid phase mechanochemical, photografting, and suspension. In actual industrial production, the benefits of quick turnaround times and continuous operation have been widely utilized.
In addition to improving the dispersion of flame-retardant particles in the resin matrix and forming a plastic interface layer that can increase the material’s toughness, PE-g-MAH can significantly increase the interfacial compatibility and interaction force of composite materials. PE-g-MAH can also enhance PE’s hydrophilicity and adhesive qualities. PE-g-MAH is currently widely utilized in polymer composites, where it serves as a dispersion, binder, and compatibilizer.
