Industry Background and Market Demand The global demand for electrical nonwoven fabrics is rising steadily, driven by expanding applications in energy storage, automotive, aerospace, and electronics. These specialized materials offer superior insulation, thermal resistance, and mechanical durability compared to traditional woven textiles. With industries increasingly prioritizing lightweight, high-performance solutions, nonwoven fabrics are becoming indispensable in electrical insulation, battery separators, and electromagnetic shielding.

The flame-retardant properties of 7031 electrical polyester fiber nonwoven fabric are primarily achieved through the material's chemical composition and physical structure. Polyester fiber itself possesses a certain degree of flame retardancy, but this can be further enhanced by adding flame retardants. At high temperatures, flame retardants decompose and release flame-retardant gases, such as nitrogen or carbon dioxide. These gases dilute the concentration of flammable gases, inhibiting the spread of flames. Simultaneously, flame retardants promote the formation of a char layer, which isolates oxygen and heat, preventing the combustion reaction from continuing. The stability of the char layer is crucial for the flame-retardant effect; high-quality flame retardants can form a dense and resistant char layer.

Industry Background and Market Demand Electrical fires remain a critical concern across industries, accounting for a significant percentage of commercial and residential fire incidents. According to the National Fire Protection Association (NFPA), electrical failures or malfunctions contribute to over 13% of structural fires annually. As regulatory frameworks like the IEC 60332 and UL standards tighten, manufacturers seek advanced materials that enhance fire resistance while maintaining performance efficiency.

Industry Background and Market Demand Electrical safety remains a critical concern across industries, from power distribution to consumer electronics.
