A high performance aromatic fibre made of the main components 1,3- phenylenediamine and isophthalic acid. DuPont, with their Nomex® brand fibre is one of the most important suppliers. In general m-AR tends to be gradually degraded under hostile flue gas conditions e. g.: combination of elevated temperatures above (140°C to 200°C and excessive moisture (>10%). Consequently filter media made of m-Aramid are frequently processed with an additional protection against acids and hydrolysis.
Dog bone-shaped fibre cross-section with good dust separating efficiency.
