Feature introduction:
High strength: The characteristic strength can reach more than 20.0CN/dtex, which is five times that of steel and more than two times that of general organic chemical fiber materials;
Low density: much lower than steel, only 1/5 of the density of steel;
Good heat resistance: under the environmental conditions of 130°C, there is basically no loss of strength. It can be used normally at 200°C. Carbonization does not occur until around 427°C and decomposes above 500°C, with no melting point;
Corrosion resistance: It will only be affected by long-term exposure or use in high-concentration acid-base environments;
UV stability: Long-term exposure to UV light can cause a loss of mechanical properties, the extent of which depends on wavelength, exposure time, radiation intensity and product geometry.
