Are polyester fabric outdoor bench materials fire-resistant without chemical treatments?

Polyester fabric, commonly used for outdoor bench materials, is not inherently fire-resistant. Unlike naturally flame-retardant fabrics such as wool, polyester is a synthetic material that can melt and ignite when exposed to high heat or open flames. Without chemical treatments or flame-retardant coatings, polyester remains highly flammable, posing a potential fire hazard in outdoor settings.

To enhance fire resistance, manufacturers often apply flame-retardant chemicals during production. These treatments can slow ignition and reduce flame spread, making polyester safer for public and commercial use. However, untreated polyester fabric should not be considered fire-resistant. For outdoor furniture in high-risk areas, choosing inherently fire-resistant materials or treated polyester is recommended for improved safety.

Always check product specifications and safety certifications when selecting outdoor bench fabrics to ensure compliance with fire safety standards.
