High termperature needle punched felt

Excellent resistance to abrasion 

Good resistance to alkalis under most condition

Most mineral oxides cause degradation and partial decomposition.

Aramid withstands common organic solvents very well. Some phenolic compounds cause solubility. 

Continuous operating temperature 400oF (204°C)

Best used in dry conditions at high temperatures
