Magnesium Hydroxide MDH-III-3

Shandong Taixing New Materials Co., Ltd. is a professional manufacturer of magnesium hydroxide MDH-III-3.

Magnesium hydroxide MDH-III-3 is a high-performance flame retardant developed based on nanosheet composite technology, with a chemical formula of Mg (OH) ₂ and a white nanoscale powder appearance (average particle size of 800nm). It constructs a triple functional system through a "core-shell layer" structural design:

-Efficient flame retardant: With a decomposition temperature of up to 380 ℃ and a 30% increase in water release and heat absorption, combined with nano synergists, the material's flame retardant rating can reach UL94 V-0 level (0.8mm ultra-thin thickness).

-Enhancement and toughening: The nanosheet layer forms an interpenetrating network structure with the polymer, increasing tensile strength by 20% and impact strength by 15%, solving the problem of "embrittlement" of traditional flame retardants.

-Food grade safety: Heavy metal content<10ppm, halogen-free, no VOCs release, certified by international food contact standards such as FDA and LFGB, suitable for highly sensitive fields such as healthcare and maternal and child care.

Physical and Chemical Properties

Application : 

1. Aerospace and Rail Transit

-Composite material components:

Used for carbon fiber reinforced epoxy resin (CFRP), adding 15-20% can meet FAR 25.853 flame retardant standard, smoke density (SDR) ≤ 15, toxicity index (IT) ≤ 2, suitable for aircraft interior panels and high-speed rail seats.

-Cable system:

Suitable for aviation grade low smoke halogen-free cables, with a flame retardant rating of EN 45545-2 R22/R23/R24 HL3, capable of withstanding 1200 ℃ flame impact for 15 minutes without penetration.

2. Electronic appliances and new energy

-5G communication equipment:

Used for the flame retardant layer of PI (polyimide) film, adding 10-15% to make the oxygen index (OI) ≥ 40% while maintaining a dielectric constant (ε)<3.0, suitable for high-frequency signal transmission scenarios.

-Power battery:

As a flame-retardant coating material for battery packs, it can suppress thermal runaway diffusion and achieve "no fire, no explosion" in needle puncture testing, complying with UN38.3 and GB/T 38031-2023 standards.

3. Medical and high-end consumption

-Medical polymer:

Used for polypropylene (PP) infusion bottles and polyethylene (PE) medical pipes, adding 8-12% can pass ISO 10993 biocompatibility testing, with flame retardant performance reaching HB level, meeting the requirements of medical sterilization environment.

-Maternal and child products:

Used in plastic parts of baby strollers and materials for children's toys, it meets the ASTM F963-17 toy safety standard and does not release harmful gases when burned, ensuring the safety of infants and young children.
