Aramid pre-oxidized fiber composite base fabric felt

Basic properties of aramid pre-oxidized fiber composite base fabric felt

① High-temperature resistance

Continuous use temperature up to 200℃, instantaneous temperature resistance 300℃, maintaining structural stability at high temperatures.

The pre-oxidation process significantly improves thermal stability; it does not shrink or melt when burning, and has excellent flame retardancy.

② Mechanical strength and durability

High radial and weft strength, and resistance to bending.

The composite fabric structure enhances tensile and wear resistance, extending service life.

③ Chemical stability

Resistant to acid and alkali corrosion and organic solvent erosion, suitable for corrosive environments.

Outstanding radiation resistance, maintaining high strength after long-term exposure.

Application fields of aramid pre-oxidized fiber composite base fabric felt

① High-temperature industrial dust removal

Incinerators: Used in bag dust collectors for steel plants (sintering, blast furnaces, converters, electric furnaces), cement plants (kiln head, kiln tail), coal/gas-fired power plants, incinerators, chemical plants, and smelters. As the core material of dust removal filter bags, it withstands acidic flue gas and high temperatures, has a long lifespan, and saves costs.

Cement plants/iron and steel plants: Can operate stably for a long time at 180°C - 250°C or even higher (depending on fiber ratio and process), handling flue gas containing high temperature, high humidity, and corrosive components (such as SOx, NOx), with high filtration efficiency and long service life. Used for kiln tail dust collection and blast furnace gas purification, withstanding alkaline dust and 200℃ fluctuations.

② Fire prevention and thermal protection

Fire suits, flame-retardant bags: Utilizing hydrophobic and fire-resistant properties.

Fire blankets/fire extinguishing blankets: Covering the fire source to isolate oxygen, or wrapping the body for escape.

Firefighting suits/heat-insulating suits: As a heat-insulating layer material, protecting firefighters or personnel in high-temperature operations from heat radiation and flame damage.

Fire curtains/fire door core materials: Providing a heat-insulating and fire-resistant barrier.

Welding protection: Welding blankets, fire curtains, etc., preventing sparks from igniting.

③ High-end industrial materials

Used as high-temperature flange gaskets, valve packing, kiln/oven door seals, and outer protection of thermal pipeline insulation layers, requiring high-temperature resistance, pressure resistance, good sealing, and resistance to aging.

Automotive sound insulation and fire protection layer: Enhancing safety and comfort.

Ship anti-corrosion layer: Resisting seawater erosion and salt spray environments.

④ Heat insulation and thermal insulation materials

Parts of industrial kilns, thermal equipment, pipelines, and aerospace vehicles that require efficient heat insulation and thermal insulation.

Engine compartment heat insulation, fire-resistant partitions, and special protective equipment, etc.
