Flame-retardant and fire-resistant aramid felt for protective curtains and welding blankets in high-temperature industrial environments.

Aramid felt is a nonwoven fabric made by needle-punching aramid fibers as the primary raw material. It boasts excellent properties such as flame retardancy, fire resistance, lightweight nature, high strength and high modulus, and softness.

Aramid felt possesses a number of outstanding characteristics and is suitable for a variety of complex, high-temperature industrial environments.

Aramid boasts exceptional high-temperature resistance and inherent flame retardancy. It doesn’t merely withstand high temperatures—it maintains long-term stability even in environments exceeding 250°C, and it won’t melt even when exposed to brief thermal shocks of up to 500°C. When directly exposed to flames, aramid chars and expands, forming a robust thermal insulation barrier that effectively blocks heat and flames, thereby slowing the spread of fire.

Building on this robust foundation of high-temperature protection, its exceptional high strength and dimensional stability provide solid structural assurance. Its fiber strength is several times that of high-quality steel, and the resulting felt form ensures outstanding tear and tensile resistance. More importantly, even under harsh operating conditions characterized by high temperatures and high humidity, it maintains a remarkably low shrinkage rate, preserving both its shape and functionality. This significantly reduces the likelihood of protective failures or sealing leaks caused by material deformation.

Its excellent electrical insulation and chemical resistance greatly expand its application boundaries. Whether in high-temperature, high-pressure electrical environments or in complex chemical scenarios involving various organic solvents and oils, aramid felt can maintain stable insulation performance and physical integrity, providing long-term, reliable protection.

All of these high-performance characteristics are achieved through a lightweight, soft, and easily processable form. Its porous, fluffy felt-like structure is not only inherently lightweight, helping to reduce weight, but also traps large amounts of still air, naturally giving rise to exceptional thermal insulation and soundproofing and noise-reduction properties. This flexible characteristic enables the material to be effortlessly cut, sewn, or molded, allowing it to conform closely to various complex curved surfaces—thus transforming the material’s outstanding intrinsic performance into practical, safe components or end products.

Applications of flame-retardant and fire-resistant aramid felt:

1. High-Temperature Protection and Fire Safety Field
It is used for making thermal insulation linings in fire-fighting suits, emergency rescue suits, and racing suits, as well as protective curtains, welding blankets, and furnace lining insulation layers for high-temperature industrial environments. Its flame-retardant and thermal-insulation properties provide critical safety protection for personnel and equipment.

2. Aerospace and High-end Transportation Vehicles
Interior thermal insulation and heat-insulating layers, fire-resistant wall materials, and sound- and heat-insulating layers for engine compartments used in aircraft, high-speed trains, and racing cars. Their lightweight and high-strength properties help reduce weight and improve efficiency while meeting stringent flame-retardant safety standards.

3. Specialized Protection and Composite Material Reinforcement

It is used to manufacture personal protective equipment such as cut-resistant gloves, arm guards, and armored protective linings. In addition, aramid felt can also be used for protective coverings in sports equipment and special vehicle hulls.

4. Industrial Sealing and Friction Materials
Leveraging its high-temperature resistance and wear resistance, it is used to manufacture high-temperature pump valves, static sealing gaskets for reactors, and dynamic sealing rings. At the same time, it also serves as a reinforced substrate for producing high-performance brake pads and clutch discs, providing a stable coefficient of friction and excellent resistance to fade.

5. Filtration of high-temperature gases and liquids

In industries such as chemical engineering, metallurgy, and waste incineration, baghouse filter bags are used to treat high-temperature flue gases (reaching temperatures of 200°C or higher). These bags feature excellent temperature and chemical resistance, effectively filtering dust, protecting downstream equipment, and extending the service life of the filter bags.

6. Electronics, Electrical Engineering, and New Energy fields

Used as an insulating and thermal-protective material for high-performance motors, transformers, and battery packs—especially power batteries—to prevent the spread of thermal runaway. In lithium batteries, it can serve as a thermally insulating and flame-retardant layer between cells, thereby enhancing the overall safety level of the battery pack.
