Aramid fiber

Kevlar fiber
Aramid is a brand name of aramid fiber material product which is DuPont company developed. It is the registered trademark for a para-aramid synthetic fiber.




Mechanical properties:
Strength: 3.6 GPa; Elongation modulus: 131 GPa; Elongation at break: 2.8%

Thermal properties:
Long time working temperature: 180℃;
Axial thermal expansion coefficient: -2 × 10 ^ (-6) / K;
Thermal conductivity: 0.048 W(m·K);

Feature of Aramid:
Permanent heat resistant and flame resistant; Limiting oxygen index(Loi) is more than 28; Permanent anti static; Permanent chemical resistant; High strength, high cut resistant, high tear resistant; Aramid fiber is no molten drop on fire and does not produce toxic gas; When the fabric on fire, it will thickening, not broken and enhance sealing property.
