NINGBO INNO PHARMCHEM CO.,LTD. is proud to present its advanced MAH Grafted SEBS (Styrene Ethylene Butylene Styrene grafted with Maleic Anhydride), a high-performance functionalized polymer designed to significantly enhance the properties and processability of various plastic systems. Known technically as SEBS-g-MAH, this specialized material serves multiple critical roles in modern polymer science, primarily as a powerful adhesive agent and an effective impact modifier.

MAH Grafted SEBS is a key ingredient in applications requiring superior adhesion between dissimilar polymer substrates. One of its prominent uses is as an adhesive agent for TPE over molding. Over molding, the process of molding one material over another, often involves combining soft thermoplastic elastomers (TPEs) with rigid substrates such as polypropylene (PP), polyethylene (PE), or polyamides (PA). Achieving a strong, durable bond between these often incompatible materials is challenging. MAH Grafted SEBS provides the necessary chemical compatibility and bonding strength, creating robust adhesion through the interaction of the polar maleic anhydride groups with polar substrates or functional groups on other polymers, while the SEBS backbone ensures compatibility with the elastomeric phase. This results in improved product integrity, feel, and performance in applications ranging from consumer goods and electronics to automotive parts.

Beyond its adhesive capabilities, MAH Grafted SEBS is widely recognized as a highly effective impact modifier, particularly for engineering plastics like polyamides (PA6, PA66). Polyamides, while possessing excellent mechanical strength, stiffness, and thermal resistance, can sometimes exhibit brittleness, especially at low temperatures or when reinforced with fillers like glass fibers. The incorporation of MAH Grafted SEBS significantly enhances the toughness and impact strength of polyamides without substantially compromising other desirable properties. The dispersed SEBS-g-MAH particles act as stress concentrators, absorbing impact energy and preventing crack propagation. The maleic anhydride grafts ensure good dispersion and strong interfacial adhesion between the SEBS phase and the polyamide matrix, which is crucial for efficient impact modification. This makes SEBS-g-MAH indispensable in applications requiring high durability and resistance to sudden shocks, such as automotive components, electrical connectors, and industrial parts.

Furthermore, MAH Grafted SEBS functions as a valuable compatibilizer in polymer blends. Many polymers are immiscible, meaning they do not mix well, leading to poor morphology, reduced mechanical properties, and processing difficulties when blended. As a compatibilizer, SEBS-g-MAH helps to bridge the gap between incompatible polymer phases. For instance, in blends of polyamides and polyolefins or PPO/PA blends, the MAH groups can react or interact with the polar polyamide or PPO phases, while the SEBS block is miscible with the polyolefin or SEBS block within the blend. This interaction stabilizes the interface between the phases, leading to a finer dispersion, improved morphology, and consequently, enhanced overall performance of the polymer alloy or blend.
