Durable thermal stability. The most prominent feature of aramid 1313 is its high temperature resistance, which can be used for a long time at a high temperature of 220 ℃ without aging. Its electrical and mechanical properties can be maintained for up to 10 years, and its dimensional stability is excellent. At around 250 ℃, its thermal shrinkage rate is only 1%; Short term exposure to high temperatures of 300 ℃ will not cause shrinkage, embrittlement, softening, or melting; It only begins to decompose at temperatures exceeding 370 ℃; Carbonization only begins at around 400 ℃ - such high thermal stability is rare in organic heat-resistant fibers.

Proud flame retardancy. The percentage of oxygen required for a material to burn in air is called the limit oxygen index, and the higher the limit oxygen index, the better its flame retardant performance. Usually, the oxygen content in the air is 21%, while the limit oxygen index of aramid 1313 is greater than 29%, making it a flame-retardant fiber. Therefore, it will not burn in the air or aid in combustion, and has self extinguishing properties. This inherent characteristic derived from its own molecular structure makes aramid 1313 permanently flame retardant, hence it is known as a "fireproof fiber".

Excellent electrical insulation. Aramid 1313 has a very low dielectric constant and its inherent dielectric strength enables it to maintain excellent electrical insulation under high temperature, low temperature, and high humidity conditions. The insulation paper prepared with it can withstand breakdown voltage up to 40KV/mm, making it the globally recognized best insulation material.

Outstanding chemical stability. The chemical structure of aramid 1313 is exceptionally stable, resistant to the corrosion of most highly concentrated inorganic acids and other chemicals, and resistant to hydrolysis and steam corrosion.

Excellent mechanical properties. Aramid 1313 is a flexible polymer material with low stiffness and high elongation, which gives it the same spinnability as ordinary fibers. It can be processed into various fabrics or non-woven fabrics using conventional spinning machines, and is wear-resistant and tear resistant, with a wide range of applications.

Super strong radiation resistance. Aramid 1313 resistant α、β、χ The performance of radiation from radiation and ultraviolet light is excellent. Using 50Kv χ After 100 hours of radiation, the fiber strength remained at its original 73%, while the polyester or nylon had already turned into powder.
