Maleic Anhydride Grafted Polypropylene (PP-g-MAH) is a widely used coupling agent in the plastics industry. It is created by grafting maleic anhydride onto polypropylene, enhancing its adhesion to other materials like fillers and reinforcements. This modification improves the interfacial bonding between polypropylene and other substances, making it a key material in creating high-performance composite materials.
