Magnesium Hydroxide Is Recommended As A Flame Retardant For The Insulating Base Of Copper Terminal Blocks.

Magnesium hydroxide, as a halogen-free flame retardant, is more environmentally friendly and suitable for high-reliability electrical components compared to traditional halogen-containing flame retardant systems. Studies show that magnesium hydroxide releases water vapor during its thermal decomposition, thus inhibiting the combustion process. In the insulation base structure of copper terminal block, the introduction of magnesium hydroxide can enhance the local material's reaction response under high temperatures or fire sources.

From a material matching perspective, copper distribution block insulation bases typically employ a polymer-based structure, while magnesium hydroxide can be physically ultrafinely pulverized and fully dispersed in the matrix, improving the overall structural uniformity. Ultrafine magnesium hydroxide powder with a Mg(OH)₂ content of over 96 wt% and an average particle size of 0.5-1 μm is used in cable resin formulations. In devices like copper terminal strip, which have high requirements for electrical performance and insulation stability, the uniform dispersion and compatibility of the base material are particularly important.
