Aramid fiber , F-12 Aramid fiber for personal protection purpose
F-12 aramid fiber is known as aromatic polyamides. Its properties led to wide use in protective clothing, insulation and as a replacement for asbestos.
Properties
The chemical structure of the chain molecules is such that the bonds are aligned (for the most part) along the fiber axis, giving them outstanding strength, flexibility and abrasion tolerance. With outstanding resistance to heat and low flammability, they are unusual in that they do not melt – they merely start to degrade (at about 500 degrees Centigrade).
They also have very low electrical conductivity making them ideal electrical insulators.
With high resistance to organic solvents, the all-round ‘inert’ aspects of these materials offer outstanding versatility for a huge range of applications. The only blot on their horizons is that they are sensitive to UV, acids, and salts.
