Polyamides, such as PA6 and PA66, are widely recognized for their excellent mechanical properties, including high strength, stiffness, and good thermal resistance. However, in certain applications, their inherent brittleness can be a limiting factor, particularly under impact loading. To overcome this, the use of specialized impact modifiers is crucial. NINGBO INNO PHARMCHEM CO.,LTD. offers advanced impact modifiers, notably those derived from maleic anhydride modified polyolefins, which are highly effective in enhancing the toughness of polyamides. These materials play a vital role in widening the application range of polyamides in demanding environments.

Impact modifiers are additives designed to increase the energy absorption capacity of a material, thereby improving its resistance to fracture from sudden impacts. For polyamides, which can exhibit significant notch sensitivity, impact modifiers are essential for applications where components might be subjected to drops, shocks, or vibrations. Our maleic anhydride modified polyolefins (PO-g-MAH) are formulated to achieve this by creating specific microstructures within the polyamide matrix. When blended, these modifiers can form distinct phases that act as energy sinks, diffusing the impact energy and preventing crack propagation.

The efficacy of PO-g-MAH as an impact modifier stems from its dual functionality. The maleic anhydride groups provide compatibilization with the polar polyamide matrix, ensuring good dispersion and adhesion at the phase boundaries. This intimate interaction allows the modifier to effectively participate in the energy dissipation mechanisms during impact. The polyolefin backbone contributes to the flexibility and toughness of the modifier itself, further aiding in energy absorption. This combination results in a significant improvement in impact strength, such as Izod or Charpy impact values, without unduly compromising other key properties like tensile strength or modulus.

Furthermore, the use of these impact modifiers is particularly beneficial when polyamides are reinforced with fillers like glass fibers. While glass fibers enhance stiffness and strength, they can sometimes increase the brittleness of the composite. Our PO-g-MAH products, acting as both coupling agents and impact modifiers, ensure that the composite retains a good balance of properties, offering both high strength and improved toughness. This is critical for applications in the automotive sector, where components need to be lightweight, strong, and resistant to impacts.
