Flame Retardant MDH-III-10

The flame retardant MDH-III-10 (high-purity modified magnesium hydroxide) produced by Taixing is specifically developed to address industry-wide pain points in achieving halogen-free flame retardancy for high-performance engineering plastics (such as PA, PBT, PPO) and specialty polyolefins, including poor melt flow under high filler loading, frequent surface defects in products, and significant loss of mechanical properties (especially impact strength). Combining four core values—flame retardancy, smoke suppression, reinforcement, and environmental compliance—it is widely applicable to key sectors such as power cables, new energy vehicles, construction materials, electronic appliances, and energy storage devices, serving as an integrated flame retardant and reinforcement solution for high-end engineering plastics.

Core strengths

Three-phase synergistic flame retardancy

- High-temperature stable heat absorption: Begins decomposing at 345°C (peak at 440°C), far exceeding ATH's 220°C decomposition temperature, suitable for high-temperature processing systems such as PP, PA, PC, and XLPE. With a heat absorption capacity of 1380J/g per unit mass, it can rapidly interrupt the combustion chain reaction, providing ample safety margins for high-temperature scenarios like new energy battery packs and high-voltage cables;

Low smoke, non-toxic, and environmentally friendly: When burned, it only releases clean water vapor without emitting toxic gases such as hydrogen halides or dioxins. The smoke density ratio (SDR) is ≤125, and the smoke toxicity meets the GB/T 20284-2006 ZA1 level (lowest toxicity). It addresses the core issue of halogenated flame retardants' combustion pollution, making it suitable for densely populated areas such as hospitals, subways, and schools;

- Densified Carbon Layer Protection: Utilizing supercritical fluid crystallization technology to form regular hexagonal flake crystals (diameter-to-thickness ratio 11:1), the decomposed magnesium oxide (MgO) particles synergize with phosphorus-nitrogen co-effectors to create an inorganic carbon layer with a 55% enhanced density.

2. Outstanding Performance Improvement

-High thermal stability and reliability: The initial decomposition temperature of the product is ≥ 345 ° C, and the thermal decomposition curve is gentle, providing a spacious safety window for the processing of high-temperature engineering plastics. The surface treatment layer can withstand processing temperatures above 300 ° C without decomposition or the production of volatile substances, ensuring the stability of the production process and the absence of odor in the product.
