Aramid needle felt
Description
The fabrics of Aramid Needle Felt is not flammable nor ignition, suitable for high temperature environment.Aramid (commonly known as: aromatic polyamide fiber), long-term temperature 204 ℃, instantaneous temperature 240 ℃, alkali resistance strong, medium acid resistance, is the treatment of 180-220 ℃ high temperature gas good material.
Features of aramid needle felt:
Compare with the other heat-resisting fabrics, Aramid needle felt is cheaper and better. Good performances of intensity. Good abrasion and folding resistance. The acid resistance of our aramid needle felt is good.
