Standard Felt

Meta Aramid is a high temperature fiber, suitable up to 200°C in dry conditions; care is needed when used in moist environments at high temperatures as it is prone to hydrolysis which will chemically degrade the fibers.

The original fiber was known as Nomex® from DuPont though today a number of alternative fibers with the same basic chemistry are available so many applications simply specify "aramid". The fiber is self-extinguishing with an LOI of around 30%.

Susceptible to hydrolysis in high temperature environments where acid can act as a catalyst – used in the asphalt, cement, quarry and smelting industries.
