MDH, Magnesium Hydroxide, HS Code: 281610, MC Series Small Specific Surface Area High Dispersibility Magnesium Hydroxide

Silane treatment (e.g., MF-3S, MC-1S) enhances chemical bonding between filler and polar polymers, improving mechanical strength and elongation at break; stearic acid modification (e.g., MF-3Y) is cost-effective and versatile, suitable for high-volume general flame retardancy needs; functional polymer modification (e.g., MF-3H) greatly improves filler dispersion uniformity in the matrix, ideal for applications demanding exceptional mechanical performance.

In low-smoke halogen-free cable compounds, the typical loading is 50%~65% by weight; in PVC cable compounds, generally 30%~50%; in general thermoplastics, 30%~60% depending on the required flame retardancy rating. Higher loading improves flame retardancy but may affect processability and mechanical properties, which is typically balanced through surface modification.

The MC series (D50 approx. 1~1.5um, 99%) offers three key improvements over the MF series (D50 approx. 3~9um, 91%): first, smaller particle size and lower specific surface area enable more uniform dispersion in polymers; second, higher purity achieves LOI up to 40 for superior flame retardancy; third, less impact on mechanical properties, preserving elongation and tensile strength, making it ideal for high-performance applications such as automotive electronic wires and...
