Meta-aramid felt is a needle-punched nonwoven made from Nomex meta-aramid fiber 1313. It is a high-performance industrial felt with excellent continuous heat resistance, inherent flame retardancy, ultra-low thermal shrinkage, and outstanding abrasion & flex resistance. Under sustained high temperatures, it will not melt or soften and maintains stable dimensions, significantly outperforming regular polyester felt and wool felt. Available in rolls, endless conveyor belts, thermal gaskets, and filter media, it is widely used in heat transfer printing, high-temperature pressing, thermal insulation, and high-temperature dust filtration.

Chemical properties: | Stable against common weak corrosive substances, but vulnerable to high-concentration strong acid and boiling strong alkali. |
1. Flame retardancy: carbonizes only above 400°C; limiting oxygen index: 30.
2. Non-combustible and non-flammable.
3. Chemical resistance: resists weak acids, weak alkalis, sulfide flue gas, and organic solvents; suitable for acidic high-temperature flue gas environments.
4. Wear & tear resistance: high toughness, excellent bending resistance, and long service life.
5. Electrical insulation & thermal insulation: excellent insulating and heat-retaining performance, with good moisture resistance.
6. Air permeability & easy dust cleaning: 3D porous structure, high air-flow rate, high dust-removal efficiency, and large dust-holding capacity.
1. High-temperature dust removal: filter bags/filter media for asphalt mixing plants, cement plants, steel smelting, power plants, non-ferrous metal smelting, and chemical kilns.
2. High-temperature industrial conveying: aluminum extrusion conveyor blankets, drying equipment transmission blankets, and ironing blankets.
3. Heat insulation, insulation & sealing: high-temperature gaskets, insulating pads, heat-insulating buffers, and sealing liners.
4. Wear-resistant protection: high-temperature wear strips, anti-slip pads, and polishing buffers.
