In the dynamic field of polymer science and manufacturing, achieving optimal material performance often requires sophisticated chemical modifications. Poly(ethylene-alt-maleic anhydride), commonly known as PE-alt-MAH or Maleic Anhydride Grafted Polyethylene (MAH-PE), with CAS number 9006-26-2, stands out as a highly versatile copolymer. Its unique chemical structure, featuring alternating ethylene and maleic anhydride units, equips it with remarkable reactivity and compatibility, making it an indispensable additive for a wide array of plastic modification applications. As a professional supplier of these advanced materials, we are dedicated to providing high-quality PE-alt-MAH to manufacturers seeking to enhance their product offerings. If you are looking to buy cost-effective solutions for plastic modification, exploring our product line is essential.

The primary function of PE-alt-MAH is that of a coupling agent. In composite materials, particularly those involving polymers and inorganic fillers like glass fibers, mineral powders, or wood flour, there is an inherent incompatibility. The maleic anhydride groups in PE-alt-MAH can react with hydroxyl groups present on the surface of these fillers, while the polyethylene backbone ensures compatibility with the polymer matrix. This chemical bridging drastically improves the interfacial adhesion between the filler and the polymer. The result is a significant enhancement in the mechanical properties of the composite, including improved tensile strength, flexural modulus, and impact resistance. This is particularly relevant for applications in automotive components, construction materials, and consumer goods where performance and durability are critical.

Beyond its role as a coupling agent, PE-alt-MAH also serves as an effective impact modifier for engineering plastics, especially polyamides (nylon). By integrating into the polymer matrix, it can absorb impact energy, thereby increasing the toughness and reducing the brittleness of the material without significantly compromising its stiffness or thermal properties. This makes it ideal for components that require both strength and resilience. Manufacturers can buy our PE-alt-MAH to achieve a better balance of properties in their nylon formulations, extending product life and reducing failure rates.

Furthermore, PE-alt-MAH finds application in coextrusion processes as a tie-layer resin. It promotes excellent adhesion between dissimilar polymers, such as polyethylene and EVOH or polyamides, which is vital for multi-layer films and packaging. This capability helps create robust barrier properties in packaging materials, extending shelf life and preserving product quality. The ability to dilute PE-alt-MAH with LLDPE or LDPE also offers flexibility in formulation, allowing users to tailor the properties to specific processing requirements. For businesses keen on sourcing these versatile materials, understanding the competitive pricing and reliable supply chain from manufacturers in China is key.
