In the field of modern industrial materials, safety and environmental protection have become key criteria for assessing product value.
In the realm of modern industrial materials, safety and environmental protection have become key criteria for assessing product value. Luoyang Xuantai New Materials Technology Co., Ltd.’s flagship product—ultrafine, high‑whiteness aluminum hydroxide—serves as a high‑performance, environmentally friendly inorganic flame retardant and, thanks to its unique physicochemical properties, plays a vital role across numerous critical industries.
The flame‑retardant mechanism of ultrafine, high‑whiteness aluminum hydroxide is primarily based on its endothermic decomposition. When the ambient temperature reaches a certain threshold, the material decomposes, releasing crystalline water. This process not only absorbs substantial amounts of heat, effectively lowering the surface temperature of the material, but also generates water vapor, which dilutes the oxygen concentration in the combustion zone, thereby inhibiting the continuation of burning. Furthermore, the alumina protective layer formed upon decomposition provides an additional barrier, isolating heat and oxygen and offering dual protection to the substrate.
Thanks to the company’s advanced manufacturing processes and centralized control system, Xuantai New Materials’ ultrafine, high‑whiteness aluminum hydroxide boasts superior purity, excellent whiteness, and a narrow particle size distribution. These characteristics ensure outstanding dispersibility and compatibility when used as a filler in polymeric materials, delivering excellent flame‑retardant performance while minimizing any adverse impact on the substrate’s original physical and mechanical properties. Currently, this product is widely employed in wire and cable applications, industrial coatings, ceramics, and electronic products, among other fields.
