Aramid fiber
KERMEL
Kermel® is a naturally non-flammable fibre. Non-flammability is a permanent characteristic thanks to Kermel's chemical structure including a high proportion of aromatic structures and combined double bonds.
Kermel is a smooth-surfaced fibre with an almost circular cross-section. This shape, as well as its modulus, makes it comfortable and very pleasant to the touch.
The non-flammable fibre has a very high resistance to abrasion, a thermal conductivity twice as low as any other aramid fibre. It also has an excellent resistance to chemicals.
Kermel® aramid fibre is solution-dyed during the manufacturing process for lifelong colourfastness .
Colours of non-flammable Kermel fibres can withstand UV lights and washing.
KERMEL manufactures two different fire resistant fibres for two separate applications.
Kermel® Tech is an aromatic polyimide-amide fibre, resulting from polycondensation of toluylene diisocyanate and trimellitic anhydride.
Kermel® is a polyamide-imide, classified in the meta-aramid family.
Non-flammable Kermel® Tech can withstand high temperature in the long run (several years), whereas fire resistant Kermel® fibre can resist extreme high temperatures (up to 1,000°C) during a few seconds.
Kermel® Tech is used for technical applications such as hot gas filtration, while Kermel® is dedicated to protective clothing against heat and flames.
Mechanical properties of Kermel® Tech
Non-flammable Kermel® Tech fibre has an excellent resistance to abrasion thanks to its amorphous structure and its high elongation at break.
