1.Magnesium Hydroxide For General Plastics acts as an eco-friendly flame retardant by decomposing endothermically (at ~340°C), releasing water vapor to cool the material and forming a protective MgO char layer. 2.Effective flame resistance demands high filler content, Magnesium Hydroxide For General Plastics can reduce mechanical properties (e.g., impact strength, flexibility) and increase melt viscosity. 3.Magnesium Hydroxide For General Plastics Often modified with silanes or fatty acids to improve dispersion in polymers like nylon (PA), PP, and PBT, enhancing flame retardancy and processing. 4.Unlike halogenated flame retardants, PE foaming grade Magnesium Hydroxide produces minimal smoke and no corrosive gases, making it ideal for electronics and automotive applications. 5.PE foaming grade Magnesium Hydroxide Combined with melamine polyphosphate, nanoclays, or intumescent additives to reduce loading while maintaining flame retardancy, especially in high-performance plastics.

Flame retardant magnesium hydroxide is widely used as a halogen-free flame retardant in engineering plastics due to its eco-friendly nature, smoke suppression, and thermal stability. Below is a detailed breakdown of Flame retardant magnesium hydroxide's role, benefits, and challenges in engineering plastics like nylon (PA), polypropylene (PP), polyethylene (PE), PBT, and others.


1. Key Properties & Flame Retardant Mechanism

How Flame retardant magnesium hydroxide Works in Engineering Plastics

  • Endothermic Decomposition:

  • Decomposes at ~340°C, absorbing heat:

Mg(OH)2→MgO+H2OMg(OH)2→MgO+H2O

  • Flame retardant magnesium hydroxide released water vapor cools the material and dilutes flammable gases.

  • Char Formation:

  • Magnesium hydroxy For Engineering Leaves a protective MgO layer, insulating the polymer from further burning.

  • Low Smoke & Toxicity:

  • Unlike halogenated flame retardants, Magnesium hydroxy For Engineering produces minimal smoke and no corrosive gases.


2. Applications in Engineering Plastics

A. Nylon (PA6, PA66)

  • Magnesium hydroxy For Engineering Used in electrical connectors, automotive parts, and industrial components.

  • Challenges:

  • High loading reduces mechanical strength (impact, tensile).

  • Magnesium hydroxy For Engineering Requires surface treatment (silanes, stearates) for better dispersion.

B. Polypropylene (PP) & Polyethylene (PE)

  • PE foaming grade Magnesium Hydroxide Common in cables, wires, and construction materials.

  • Synergists: PE foaming grade Magnesium Hydroxide Often combined with intumescent systems (e.g., APP/PER) to reduce loading.

C. PBT & PET (Thermoplastic Polyesters)

  • Magnesium hydroxy For Engineering Used in electronic housings, switches, and automotive parts.

  • Processing Challenge: High filler loading increases melt viscosity.

D. Other Engineering Plastics (PPS, PEEK)

  • Limited use due to high processing temperatures (PPS: 300°C+, PEEK: 380°C+).

  • May require modified Mg(OH)₂ grades with higher thermal stability.
