PPS (Ryton) Needle Felt

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