Retardant Polyimide Fiber For Protective Clothing
The flame-retardant polyimide fiber for protective clothing has a limiting oxygen index (LOI) of up to 38 percent.
The flame-retardant polyimide fiber of protective clothing will carbonize without melting droplets when exposed to high-temperature open flames. It will self-extinguish when removed from the fire and is non-toxic.
Flame-retardant polyimide fiber for protective clothing can ensure that the fabric has good mechanical properties and dimensional stability in high and low-temperature environments.
1. Product Introduction
Retardant polyimide fiber for protective clothing has good thermal oxidation resistance, corrosion resistance, and UV resistance, making it an ideal material for making protective clothing.
Flame-retardant polyimide fiber for protective clothing is suitable for fire-fighting clothing, petrochemical clothing, metal smelting safety clothing, furnace clothing, and fire-proof decorative materials.

3. Product Feature
Retardant polyimide fiber for protective clothing has high and low-temperature resistance, flame retardancy, no dripping, self-extinguishing when removed from fire, and excellent temperature insulation.
Protective clothing: Retardant polyimide fiber thermal insulation protective clothing is comfortable to wear, has good skin adaptability, is permanently flame-retardant, is dimensionally stable, has good safety, and has a long service life.
Compared with other fibers, the retardant polyimide fiber itself for protective clothing has a low thermal conductivity and is also an excellent thermal insulation material.
4. Product Details
Protective Clothing retardant Polyimide Fiber In terms of labor protective clothing, my country's metallurgical sector needs 50,000 sets of insulating, breathable, soft flame-retardant work clothes every year, and the hydropower, nuclear industry, geology and mining, petrochemical, oil fields, and other sectors need 30 Thousands of sets of protective clothing are required, and about 300t of retardant polyimide fiber for high-temperature resistant and flame-retardant special protective clothing is needed annually.
Non-woven fabrics made of retardant polyimide fiber for protective clothing are the most ideal fiber materials for making fire-retardant and retardant clothing such as protective clothing for armored forces, racing flame-proof clothing, and flight suits.
Retardant polyimide fiber for protective clothing can also be used to make comfortable and warm functional clothing, such as military clothing, medical hygiene clothing, casual clothing to eliminate bad body odor, special clothing to prevent biological and chemical weapons, medical hygiene protective clothing, and efficient smoke protection Masks, etc.
