High Performance Aluminum Hydroxide for Flame Retardant and Functional Material Applications

Aluminum Hydroxide (ATH, Al(OH)₃) is one of the most widely used environmentally friendly inorganic flame retardants in the world. With excellent smoke suppression performance, low toxicity, and good processing compatibility, ATH plays an important role in plastics, cables, rubber, coatings, and composite materials.

Weifang Wanfeng New Material Technology Co., Ltd. specializes in the production and supply of high-quality Aluminum Hydroxide with stable chemical properties, controlled particle size distribution, and excellent application performance. Our ATH products provide reliable solutions for customers seeking safe, efficient, and sustainable flame retardant materials.

Advanced Halogen-Free Flame Retardant Material

As a halogen-free flame retardant, Aluminum Hydroxide works through an endothermic decomposition mechanism.

When exposed to high temperatures, ATH releases chemically bound water, absorbing a large amount of heat and reducing the surface temperature of the material. At the same time, the generated alumina layer acts as a protective barrier, slowing down flame propagation and reducing smoke generation.

Key advantages:

• Halogen-free and environmentally friendly

• Low smoke emission

• Low toxicity

• Excellent flame retardant efficiency

• Good electrical insulation properties

• Stable chemical performance

Excellent Performance Advantages

1. Superior Flame Retardant Performance

Aluminum Hydroxide provides effective flame resistance for polymer materials by:

• Absorbing heat during decomposition

• Diluting combustible gases

• Forming a protective ceramic-like layer

• Reducing flame spread

It is widely used in applications requiring high fire safety standards.

2. Excellent Smoke Suppression Capability

Compared with many traditional flame retardants, ATH generates very low smoke during combustion.

It helps reduce:

• Smoke density

• Toxic gas release

• Fire hazards

Making it suitable for applications where safety is critical.

3. Good Electrical Insulation Properties

Due to its excellent electrical characteristics, ATH is widely used in:

• Cable compounds

• Electrical insulation materials

• Electronic components

It helps maintain stable electrical performance while improving flame resistance.

4. Stable Processing Performance

Our ATH products feature:

• Controlled particle size distribution

• High purity

• Good dispersion

• Consistent quality

Providing excellent compatibility with different polymer systems.
