What resin fillers improve the fire resistance of WPC outdoor armchairs?

When it comes to enhancing the fire resistance of Wood-Plastic Composite (WPC) outdoor armchairs, selecting the right resin fillers is crucial. Flame retardant additives such as aluminum trihydroxide (ATH), magnesium hydroxide, and intumescent fillers are commonly used to improve the fire safety of WPC materials. These additives work by releasing water vapor or forming a protective char layer when exposed to heat, thereby slowing down combustion. Additionally, borate-based compounds and phosphorus-containing fillers can further boost flame resistance. Incorporating these materials into WPC armchairs not only meets safety standards but also extends the lifespan of outdoor furniture. For optimal performance, a balanced combination of these fillers is recommended to ensure both fire resistance and structural integrity.
