Meta-aramid is an aromatic polyamide fiber which possesses excellent physical and mechanical properties . It can be applied widely in filtration, thermal protective apparel and honeycombed structure materials,etc.
Heat resistance Meta-aramid fibre offers outstanding heat resistance, being resistant to melting even after many hours of exposure to heat. 75% of original strength is retained after exposure to dry-heat of 200°C for 1000 hours.
Flame resistance The Limiting Oxygen Index (LOI) of Meta-aramid fibre is over 28%. It will not burn, melt or drip. Above 370°C They will start to carbonise and decompose.
Heat insulating properties They have excellent heat insulating properties. These and its high dielectric strength enable Class-H (up to 180°C) insulating paper to be manufactured from it.
Resistance to chemicals It exhibits very good resistance to many chemicals. It is resistant to most strong inorganic acid and shows excellent resistance to alkalis at room temperature.
Good textile properties Its low stiffness and high elongation give excellent textile-like properties and characteristics, allowing processing on all types of conventional textile equipment. The staple version can be processed into yarns for the manufacture of knitted and woven fabrics as well as non-woven fabrics. Filament yarn can be converted into knitted and woven fabrics.
Radiation resistance It shows good resistance to α,β and ultraviolet radiation.
