What fire-retardant additives are used in resin-based outdoor benches?
Resin-based outdoor benches are popular for their durability and weather resistance, but fire safety is equally important. To enhance flame resistance, manufacturers often incorporate fire-retardant additives into the resin. Common additives include aluminum trihydroxide (ATH), magnesium hydroxide, and brominated flame retardants. These compounds work by releasing water vapor or forming a protective char layer when exposed to heat, slowing combustion. Additionally, phosphorus-based retardants and intumescent coatings are used for extra protection. Choosing benches with these additives ensures safer outdoor spaces while maintaining aesthetic and functional qualities. Always check product specifications for fire safety certifications.
