Modified Magnesium Hydroxide
Description
Technical Parameters
Product introduction
Modified Magnesium Hydroxide is a high-purity Mg(OH)₂ that has undergone surface treatment with specific coupling agents (e.g., silanes, fatty acids, titanates) to improve its compatibility and performance within polymer matrices. This process transforms it from a basic inorganic powder into a high-value functional additive.

Product Features
Modified Magnesium hydroxide is featured with excellent interfacial compatibility-the compatibility between modified Mg (OH)2 and polymer matrix has been greatly improved, forming a strong interfacial bonding force, which is the basis for all performance improvements. It is also featured with Superior Dispersion-The modified Mg (OH) ₂ can achieve nanoscale and uniform dispersion in the polymer matrix, eliminating stress concentration points caused by aggregates; Under the same or even higher filling amount, modified Mg (OH) ₂ can preserve the mechanical properties of the matrix polymer to the greatest extent, significantly improving the impact strength and toughness of the composite material. The modified Mg (OH) ₂ composite system has lower melt viscosity and higher flowability, making extrusion, injection molding and other processing processes smoother, lower energy consumption, and better surface finish of the product; After modification, its better dispersibility and compatibility result in higher flame retardant efficiency and denser carbon layer. It always has the environmentally friendly flame retardant characteristics of halogen-free, low smoke, and non-toxic; Modified Mg (OH) ₂ has significantly reduced moisture absorption, making it particularly suitable for applications that require high electrical performance, such as wires and cables.
