Meta-Aramid Fibers

Description

Product Features

• High Heat Resistance

Meta-aramid fibers can withstand high temperatures, typically up to 450°F (232°C), without degrading. This makes them ideal for environments exposed to heat and flames.

• Flame Retardancy

They are naturally flame-resistant, which means they do not burn easily and self-extinguish when the source of heat is removed. This makes them a popular choice in protective clothing, such as firefighter suits and industrial uniforms.

• Chemical Resistance

Meta-aramid fibers are resistant to many chemicals, oils, and solvents, making them suitable for use in chemical processing and industrial filtration applications.

• High Strength

These fibers have good tensile strength, which makes them durable and resistant to wear and tear.

• Low Abrasiveness

Meta-aramid fibers have low abrasiveness, which allows them to be used in applications that require friction-resistant materials, such as brake pads and clutch linings.

• Lightweight

Meta-aramid fibers are lightweight yet strong, making them ideal for use in textiles and composites where weight is a consideration.

Applications

• Protective clothing

One of the most common uses of meta-aramid fiber is protective clothing, such as fireproof clothing, gloves, aprons, hard hats and explosion-proof clothing. These fibers provide important heat and fire protection in industries such as firefighting, aviation and military applications.

• Filtration

Due to its heat and chemical resistance, meta-aramid fiber is widely used in industrial filters and can be processed into needle-punched nonwovens and woven filter cloths for high-temperature flue gas filtration in metallurgy, cement, construction and other fields.

• Other applications

1. Aramid needle-punched nonwovens can be processed into high-temperature resistant conveyor belts, such as endless conveyor belts, sleeves, etc.
2. It can also be made into textile high-speed printed carpets.
3. Through appropriate papermaking processes, it can be processed into insulation paper, honeycomb cores, etc.
