10 Micron Magnesium Hydroxide

The 10 micron magnesium hydroxide produced by Taixing has a lower specific surface area and surface energy compared to finer particle sizes (such as 1-3 microns). In general plastics such as PP, PE, EVA, 10 micron particles can effectively avoid stress concentration caused by the aggregation of submicron particles. While providing reliable flame retardancy, the impact on material toughness and rigidity reaches the optimal balance point. Widely applicable to large-scale application scenarios such as rubber and plastic products, building materials, wires and cables, and industrial flame retardant coatings, it is the core product of the industrial grade large particle flame retardant market.

Core strengths

1. High temperature stable heat absorption: The initial decomposition temperature is 340 ℃ (peak 438 ℃), which is suitable for the processing technology of industrial grade polymer materials such as PE, PVC, EPDM, etc. The heat absorption per unit mass can reach 1360J/g, which can quickly block the combustion chain reaction and provide sufficient safety window for high-temperature working scenarios such as mining transportation belts and building insulation materials;

2. Low smoke, non-toxic and environmentally friendly: During combustion, only clean water vapor is released, and no toxic gases or corrosive substances such as hydrogen halides and dioxins are released. The smoke density ratio (SDR) is ≤ 145, and the smoke toxicity reaches GB/T 20284-2006 ZA1 level, perfectly replacing halogenated flame retardants and suitable for personnel intensive industrial places and public buildings;

3. Excellent dispersibility: Activation index ≥ 97%, contact angle up to 152 °, surface transition from strong hydrophilic to hydrophobic oleophilic, excellent compatibility with substrates such as PE, PVC, PP, rubber, etc., dispersion uniformity increased by 40% in polymer matrix, particle size distribution span (D90/D10) ≤ 2.2, no agglomeration or delamination phenomenon, ensuring smooth appearance of the product;

4. Cost optimization advantages: The 10 micron large particle size design significantly reduces the energy consumption of grinding and grading in the production process, reducing costs by 35% -45% compared to nanoscale magnesium hydroxide; Under the same flame retardant level requirements, synergistic formula optimization can be used to control the addition amount between 40% -60%, balancing flame retardant effect and raw material cost, and reducing costs and increasing efficiency for large-scale industrial production;

5. Environmentally friendly features: The product itself is non-toxic and harmless, with an acute oral LD ₅₀ ≥ 5000mg/kg, non irritating, non corrosive, and classified as a non hazardous chemical; The decomposition products are magnesium oxide and water, both environmentally friendly substances that can be naturally degraded. After being discarded, they can be recycled as soil amendments or building fillers, achieving resource recycling.

Frequently Asked Questions (FAQ)

What is the core difference between 10 micron magnesium hydroxide and small/nano-sized magnesium hydroxide?

A1: Core differences reflected: ① Compared with nanoscale magnesium hydroxide, 10 micron products do not require complex ultrafine grinding processes, reduce costs by 35% -45%, and are less prone to secondary agglomeration, with better processing fluidity and suitability for large-scale industrial production; ② Compared with products with small particle sizes (≤ 5 μ m), 10 micron products have lower oil absorption values, less impact on the mechanical properties of the substrate with the same filling amount, lower processing energy consumption, and are more suitable for cost sensitive industrial scale large-scale application scenarios.
