Nomex high temperature needle felt is made of the fibers produced by Dupont from US or Tenjin from Japan, composited and stitched according to a certain proportion. Comparing with the common filter material, Nomex has the advantages bellowed:

1.Excellent high temperature resistance: continuous operating temperature can reach 200 degree, temperature peak up to 220 degree.

2.High stability of dimension: at the temperature of 230, only 1 percent flexibility, with excellent high temperature stability.

3.Fire retardant property: carbonization up to 400 degree, LOI is 30 ,no spontaneous or natural combustion

4.Good resistance for the chemical corrosion : anti acid and alkali , hardly corrosion .
