Polyimide staple fiber maintains the flame retardant of the fiber body while maintaining the dyeability, high temperature carbonization and non-melting droplet, extremely low combustion flue gas and almost non-toxic, good dimensional stability, high and low temperature resistance, radiation resistance, heat preservation, natural antibacterial and far-infrared and many other excellent properties.
It also has excellent properties such as insulation, weather resistance, acid and alkali resistance, and ultraviolet resistance, as well as cashmere-like feel, good spinnability and skin-friendly
Products can be used in special flame retardant protection, high temperature filtration, industrial heat insulation and civilian clothing, home textiles and health care and other fields.
Heat stability: the long-term use temperature of the paper is 260℃ and the electrical and mechanical properties are not affected. The fiber can be used in higher temperature in short time.
High and low temperature resistance, it can be used for a long time below 260 °C, the thermal decomposition temperature exceeds 567 °C, and it will not be brittle in liquid nitrogen at -269 °C;
Thermal insulation, thermal conductivity is only 0.03W/m℃, which is equivalent to air
Flame retardant: carbonized directly without burning under high temperature, the LOI is more than 38%
Excellent quality control system makes the product quality is very good and stable.
Mechanical performance: the fabric made from polyimide is abrasion-proof and has higher strength.
Chemical property: because of unique chemical structure and dry spinning technology, our polyimide fiber has better chemical resistance compared with other high performance fiber.
lrradiation resistance: because of the excellent irradiation resistance, polyimide fiber is the best material used in aerospace.
Dimensional stability: the dry heat shrinkage(280℃,30min) of polyimide fiber is less than 1%, which can guarantee the dimensional stability of filter bag.
Dyeing performance, with good dyeability, color fastness of 4-5. Compared with aramid meta aramid, the advantages are more obvious.
