Fireproof Fiber - Aramid 1313

Aramid 1313 was first developed by DuPont, USA, and it has achieved industrial production. The product was registered as Nomex. This is a kind of slender fluffy, shiny, soft and white fiber. The appearance is not obviously different from ordinary chemical fiber, but it has an extraordinary "extraordinary function":

1. Lasting thermal stability
The most outstanding feature of Aramid 1313 is its high temperature resistance, long-term use at 220 °C without aging, its electrical and mechanical properties can be up to 10 years, and its dimensional stability Excellent, the thermal shrinkage is only 1% at a high temperature of about 250°C, and it will not shrink, embrittle, soften or melt in a short time exposure to a high temperature of 300°C, but only at a strong temperature above 370°C. At the beginning of decomposition, carbonization began at about 400°C. Such high thermal stability is unique in current organic temperature-resistant fibers.

2, proud of the flame retardant
We know that the percentage of the volume of oxygen that a material needs to burn in the air is called the limiting oxygen index, and the higher the limiting oxygen index, the better its flame retardant performance. The oxygen content in the air is usually 21% and the limit oxygen index of aramid 1313 is more than 28%. It is a flame-retardant fiber, so it does not burn in the air, does not support combustion, and has self-extinguishing properties. This inherent property derived from its own molecular structure makes Aramid 1313 permanently flame-retardant, so it has the reputation of "fire-resistant fiber".

3, excellent electrical insulation
Aramid 1313 has a low dielectric constant and its inherent dielectric strength can maintain excellent electrical insulation under high temperature, low temperature, and high humidity conditions. The insulation breakdown voltage of insulating paper prepared therefrom can reach 100,000 volts. Mm, is the globally recognized best insulation material.

4, outstanding chemical stability
Aramid 1313 is a linear macromolecule composed of an amide linkage between aryl groups. In its crystal, hydrogen bonds are arranged in three planes in two planes. This strong hydrogen bond makes its chemical structure extremely stable. Highly concentrated inorganic acids and other chemicals resistant to corrosion, hydrolysis and steam corrosion.

5, excellent mechanical properties
Aramid 1313 flexible polymer material, low stiffness and high elongation properties make it have the same spinnability as ordinary fibers, can be processed into various fabrics or non-woven fabrics by conventional spinning machines, and is wear-resistant and tear-proof. Very extensive.

6, superior radiation resistance
Aramid 1313 is very resistant to alpha, beta, gamma rays, and ultraviolet radiation. When irradiated with 50 Kv helium rays for 100 hours, the fiber strength was maintained at 73%, and polyester or nylon at this time had already become a powder. The unique and stable chemical structure gives excellent performance to Aramid 1313. Through the comprehensive utilization of these characteristics, a series of new functions and new products are continuously developed. The applicable fields are more and more widespread and the degree of popularity is getting higher and higher.

7, special protective clothing
Aramid 1313 fabric does not burn, does not drip melt, and does not emit smoke in the event of fire, and it has excellent fireproof effects. Especially when the temperature of 900-1500°C is suddenly encountered, the cloth will rapidly carbonize and thicken, forming a special insulation barrier to protect the wearer from escape. If a small amount of antistatic fiber or aramid 1414 is added, the fabric can be effectively prevented from bursting, and lightning arc, arc, static electricity, flames and other hazards can be avoided. The use of aramid 1313 colored fibers can make various special protective clothing such as flight suits, chemical warfare combat suits, fire fighting suits and front work clothes, welding work clothes, pressure uniforms, radiation protection work clothes, chemical protective clothes, high pressure shielding clothes, etc. Aviation, aerospace, military service, firefighting, petrochemical, electrical, gas, metallurgy, racing, and many other areas. In addition, in the developed countries, aramid fabrics are also commonly used as hotel textiles, life-saving channels, home fireproof decorations, ironing board cladding, kitchen gloves, and flame retardant pajamas to protect the elderly and children.

8, high temperature filter material
Aramid 1313's high temperature resistance, dimensional stability and chemical resistance make it a dominant position in the field of high temperature filter materials. Aramid filters are widely used in chemical plants, thermal power plants, carbon black plants, cement plants, lime plants, and coking plants.
