Lightweight Polyimide Fibers For Transportation
Internal materials for aircraft and other transportation vehicles, including various structurally rigid three-dimensional elements, can be made of lightweight polyimide fibers for transportation;
For example, in airplanes and high-speed trains, lightness is a very important factor. These low-density, hard and fire-resistant lightweight polyimide fibers for transportation can replace traditional materials.
1. Product Introduction
Lightweight polyimide fiber for transportation has excellent flame retardant properties and a limiting oxygen index of >38%, making it a non-combustible fiber;
Lightweight polyimide fiber for transportation is resistant to high and low temperatures, can be used for a long time below 300°C, has a thermal decomposition temperature exceeding 567°C, and is not brittle in liquid nitrogen at -269°C;
The lightweight polyimide fiber used for transportation does not melt when carbonized at high temperatures, and the smoke density is 1/200 of the Chinese aviation standard;
Lightweight polyimide fiber for transportation is used for thermal insulation and warmth, with a thermal conductivity of only 0.03W/m·℃, which is equivalent to air;
Lightweight polyimide fiber for transportation also has excellent properties such as insulation, weather resistance, acid and alkali resistance, radiation resistance, and UV resistance. It also has a cashmere-like feel, good spinnability, and skin-friendliness;
Lightweight polyimide fiber for transportation is naturally antibacterial and has a much better effect than bamboo fiber;
Lightweight polyimide fiber for transportation has a natural far-infrared healthcare function, with a normal emissivity as high as 0.88.
