PPS(Ryton) Needle Felt
Our capacity:15000 square meter per day (standard PPS product)
Diameter & Length:Accept customization
PPS has good chemical stability, wide temperature range , resistance to atmospheric aging , better radiation resistance , low permeability and many other performance advantages. Despite PPS has the superior performance, the high price of PPS is its large-scale promotion of the obstacle .
Finish-treatment: Calendering, Heat setting, Singeing
