Why magnesium hydroxide needs modification or surface treatment？

Modification is divided into two kinds of wet modification and dry modification, generally commonly used modifier is coupling agent. Coupling agent can effectively reduce the apparent viscosity of the composite system, improve the fluidity of the system, polypropylene and modified nano magnesium hydroxide interface adhesion has been strengthened material tensile properties and impact strength has been increased substantially, so that the flame retardant properties have also been improved. We can also use silane-based surface modifier to magnesium hydroxide surface coating, which to a certain extent improves the dispersion and compatibility of magnesium hydroxide in EVA system and improves the flame retardant properties of the composite material.

The magnesium hydroxide and other flame retardants or flame retardant synergists through a certain method of organic combination, can significantly increase the flame retardant temperature, increase the heat absorption, reduce the amount of filling, so as to improve the flame retardant efficiency and play its comprehensive flame retardant effect.

AVANT can customize products according to customer requirements, such as surface treatment of products with different modifiers according to customer requirements; compounding ATH, MDH and smoke suppressant according to customer requirements, in order to achieve the best use effect.
