Reliable Magnesium Hydroxide for Flame Retardant Applications

Magnesium Hydroxide (MDH, Mg(OH)₂) is an environmentally friendly, halogen-free flame retardant widely used in plastics, rubber, cable compounds, and polymer materials. With excellent thermal stability, smoke suppression performance, and low toxicity, Magnesium Hydroxide has become one of the most important alternatives to traditional halogen-based flame retardants.

Weifang Wanfeng New Material Technology Co., Ltd. specializes in the production and supply of high-quality Magnesium Hydroxide with advanced processing technology and strict quality control. Our MDH products provide excellent flame retardant performance, good dispersion, and stable processing characteristics for various industrial applications.

Mineral-Based Magnesium Hydroxide with Excellent Performance

Our Magnesium Hydroxide is produced from high-quality mineral resources through advanced processing technology, ensuring consistent quality and reliable performance.

Key advantages include:

• High purity and stable chemical composition

• Excellent flame retardant efficiency

• Low smoke generation and smoke suppression capability

• Halogen-free and environmentally friendly

• Good thermal stability during processing

• Excellent compatibility with polymer systems

By releasing crystal water during combustion, Magnesium Hydroxide absorbs heat and reduces the temperature of polymer materials. At the same time, the generated magnesium oxide layer helps form a protective barrier, effectively slowing down flame spread and improving fire safety.

Applications of Magnesium Hydroxide

1. Low Smoke Zero Halogen (LSZH) Cable Compounds

Magnesium Hydroxide is widely used in low smoke halogen-free cable materials due to its excellent flame retardant and smoke suppression properties.

Applications include:

• Power cables

• Communication cables

• Railway cables

• Building cables

• Electrical wire insulation materials

MDH helps cable compounds achieve better flame resistance while reducing smoke and toxic gas emissions during combustion.

2. Flame Retardant Plastics

Magnesium Hydroxide is suitable for various polymer systems, including:

• Polyethylene (PE)

• Polypropylene (PP)

• Polyvinyl Chloride (PVC)

• EVA

• ABS

• Engineering plastics

It provides improved flame resistance while maintaining the mechanical properties of polymer materials.

3. Rubber Industry

Magnesium Hydroxide can also be used in flame retardant rubber formulations, including:

• NBR rubber

• EPDM rubber

• Chloroprene rubber (CR)

It improves fire safety performance and contributes to low smoke emission characteristics.

Customized Grades Available

We provide different grades of Magnesium Hydroxide according to customer requirements, including:

• High purity MDH

• Mineral-based MDH

• Modified Magnesium Hydroxide
