Aluminum hydroxide ( ATH ) and magnesium hydroxide ( MDH ) is currently the core of environmentally friendly, halogen-free flame retardants. However, in actual production, balancing flame-retardant performance with manufacturing costs remains a significant challenge for companies.

Vertical Ultrafine Grinder By employing a combined gravity–fluidization field technology, energy is highly concentrated within the grinding chamber. Compared with conventional processes, it can… ATH Processed to D97≤2μm It is sub-micron in size, and its particle size distribution exhibits a narrow distribution.

This kind of Energy-saving fine grinding The advantage of this method lies in the increased specific surface area of the finely ground powder, enabling the flame retardant to release water more rapidly upon heating and to form a uniform char layer. Experimental results show that the amount of flame-retardant micronized powder required in the final product can be reduced when this process is employed. 10% The above, while maintaining V0 The flame-retardant standard has significantly reduced raw material costs, helping enterprises achieve a green and low-carbon transformation.
