Ultrafine Magnesium Hydroxide Powder

The ultrafine magnesium hydroxide powder (Mg (OH) ₂) produced by Taixing is a nano level high-performance inorganic functional material, which is created using low-temperature co precipitation hydrothermal coupling crystallization+polymer graft composite modification core technology. Widely adaptable to high-precision application scenarios such as new energy batteries, electronic packaging, high-end rubber and plastic, environmental governance, etc., providing an integrated green solution of "compliance worry free+ultimate performance+scene adaptation" for global high-end manufacturing enterprises, becoming the core product of the nano functional material market.

Core strengths

1. Improvement of flame retardant efficiency

·Mechanism: The ultrafine particle size brings an exponential increase in reaction activity. When heated, the decomposition reaction is more rapid and synchronous, and the amount of heat absorbed per unit time is greater. The formed residual carbon layer (MgO) is a continuous and dense nano ceramic layer, with unparalleled barrier efficiency.

·Data: Under the same filling amount, the Limiting Oxygen Index (LOI) can be increased by 3-5 units compared to conventional 3-5 micron products; The filling amount required to achieve the same flame retardant level (such as UL94 V-0) can be reduced by 10-20%.

2. Improvement of mechanical properties of composite materials

·Enhancement rather than weakening: Ultra fine and regularly shaped plate-like crystals can serve as excellent reinforcement phases. In polymer matrices, they can effectively transfer loads, induce silver lines, and prevent their expansion, while not becoming stress concentration points due to their extremely small size.

·Result: In PA or epoxy resin systems, adding appropriate proportions can improve flame retardancy while simultaneously increasing the tensile strength, bending modulus, and hardness of the material, truly achieving "functional and structural integration".

3. Regulation of optical and surface properties

·Transparency/Translucency: When the particle size (especially thickness) is much smaller than the visible light wavelength (380-780nm), light scattering is significantly suppressed. This makes it possible to prepare highly flame-retardant, semi transparent, and even transparent composite materials in transparent matrices such as PMMA, PC, and epoxy resin.

·Ultimate surface: Completely eliminate surface defects such as "floating fibers", combined with high fluidity, to achieve a mirror like A-level appearance for the product.

4. Balance between rheology and processability

·Challenge and solution: Ultra fine particles are prone to agglomeration, which can worsen processability in traditional perception. We use our unique "steric hindrance electrostatic stabilization" dual mechanism dispersion technology to construct a stable double layer and polymer protective layer on the surface of particles, allowing them to maintain a dispersed state during storage and processing, and quickly disintegrate and uniformly disperse under shear force, ultimately achieving processing flowability superior to conventional products.
