What are the fire-retardant additives used in synthetic rattan production?

Synthetic rattan is widely used in outdoor and indoor furniture due to its durability and aesthetic appeal. However, to ensure safety, fire-retardant additives are incorporated during production. Common flame retardants include:

1. Aluminum Trihydroxide (ATH): A widely used additive that releases water when heated, cooling the material and diluting flammable gases.

2. Magnesium Hydroxide: Similar to ATH, it decomposes at high temperatures, releasing water and forming a protective char layer.

3. Phosphorus-Based Compounds: These additives promote char formation, reducing the material’s flammability.

4. Brominated Flame Retardants: Effective but less environmentally friendly, these compounds interfere with the combustion process.

5. Intumescent Additives: Expand when exposed to heat, creating a barrier that insulates the material from flames.

These additives help synthetic rattan meet fire safety standards while maintaining its flexibility and strength. Manufacturers often combine them to achieve optimal performance. Choosing the right additive depends on factors like cost, environmental impact, and specific fire resistance requirements.
