Highly Dispersed Magnesium Hydroxide

The highly dispersed magnesium hydroxide produced by Taixing is a high-performance halogen-free flame retardant, which is created using in-situ polymerization plasma activation composite modification+dynamic shear dispersion core technology. It is specially developed to solve the three major industry pain points of "flame retardancy and processability imbalance, dispersion aggregation, and high environmental compliance threshold" in polymer materials. It is widely suitable for high-precision application scenarios such as high-end rubber, new energy batteries, electronic packaging, wires and cables, and is the preferred product in the halogen-free flame retardant market.

Core strengths

1. High temperature stable heat absorption: The initial decomposition temperature is 345 ℃ (peak 440 ℃), far exceeding the 200 ℃ of aluminum hydroxide. It is perfectly adapted to the high-temperature processing technology of engineering plastics such as PP, PA, EPDM, etc. The heat absorption per unit mass reaches 1370J/g, which can quickly block the combustion chain reaction and provide sufficient safety window for high-temperature sensitive scenarios such as new energy battery packs and precision electronic devices;

2. Low smoke, non-toxic and environmentally friendly: During combustion, only clean water vapor is released, and no toxic gases such as hydrogen halides, dioxins or corrosive substances are released. The smoke density ratio (SDR) is ≤ 125, and the smoke toxicity reaches GB/T 20284-2006 ZA1 level. No additional smoke suppressants need to be added, and a single raw material can achieve a dual effect of "flame retardant+smoke suppression", suitable for precision equipment and personnel intensive places in enclosed spaces;

3. Dense barrier protection: By using directional crystallization control technology to shape regular hexagonal plate-like crystal structures, the density of the decomposed magnesium oxide ceramic layer is increased by 50%. The structural integrity can be maintained for ≥ 130 minutes in a 1000 ℃ flame environment, effectively blocking heat and oxygen transfer while suppressing droplet phenomena, significantly improving the flame retardant reliability of the material.

4. Excellent dispersibility: Activation index ≥ 99%, contact angle up to 158 °, surface transition from strong hydrophilic to hydrophobic oleophilic, excellent compatibility with high-end substrates such as PP, PA, TPE, polyolefin, etc., dispersion uniformity ≥ 98% in polymer matrix, particle size distribution span (D90/D10) ≤ 1.7, no agglomeration phenomenon, ensuring smooth appearance and stable performance of the product;

5. Strong processing adaptability: With an oil absorption value as low as 20mL/100g, it can significantly increase the melt flow rate (MFR) of composite materials by more than 40%, reduce equipment torque and energy consumption during extrusion, injection molding, and mixing processes, reduce mold wear, and adapt to high-end precision manufacturing high-speed production lines (screw speed>600rpm), greatly improving production efficiency;

6. Multi specification precision customization: The particle size D50 can be precisely controlled within the range of 0.3-5 μ m, and highly dispersed nanoscale (D50 ≤ 1 μ m) products are suitable for electronic packaging and battery separators. Conventional high dispersion products are suitable for high-end rubber, wire and cable; We can provide sub models such as "flame retardant special type", "battery grade special type", "elastomer special type", etc. The addition amount of elastomer special type can be reduced to 30% to achieve V0 level flame retardant, and the elongation at break can be maintained at 500% or above;

7. Scene adaptation: Provide functional products such as weather resistant, low dust, and high whiteness types. Weather resistant products have stable performance in extreme environments ranging from -60 ℃ to 230 ℃, and no performance degradation is observed through temperature cycling tests between -40 ℃ and 125 ℃; Low dust products with a dust flying volume of ≤ 1.5mg/m ³ comply with OSHA occupational health and safety standards; High whiteness products with a whiteness of ≥ 97.5% are suitable for high-end decorative materials and electronic device casings with strict appearance requirements.
