EVA foam products require flame retardancy, such as EVA foam packaging materials. Flame retardants can be added to the formulation to achieve flame retardant effects. The commonly used flame retardant, aluminum hydroxide, is used in a relatively large amount in foaming materials.
Maleic anhydride grafted EVA is used in halogen-free flame-retardant filler composite materials such as aluminum hydroxide and magnesium hydroxide to improve the compatibility and adhesion between the polyolefin matrix and the inorganic flame-retardant interface. Improve the dispersibility and compatibility of magnesium hydroxide and aluminum hydroxide, thereby maximizing the flame retardancy of EVA foam materials, reducing smoke index, smoke generation, heat generation, and carbon monoxide production, and increasing oxygen index. Improve dripping performance, etc.
