Experimental Study on the Durability Performance of PPS Filter Media

The durability performance of PPS filter media is experimentally studied in the paper. It is found that, under 200°C and atmospheric condition, both machine direction strength and transverse direction strength of PPS increase at the beginning and then gradually decrease with the increase of duration time. The transverse direction change for both strength and elongation is higher than the machine direction. The melting point of PPS decreases with the increase of duration time. And the melting point can be taken as one of durability index for the PPS filter media.
