Made from expanded PTFE fiber. It standing much high linear speed , pressure and temperature.  It can use a silicone core to improve compressibility and recovery, or impregnated with heatproof lubricant to reduce friction. It is widely used in chemical, food, pharmaceutical, petrochemical and other fields due to its excellent chemical stability, corrosion resistance, aging resistance, no pollution etc.FP-550      (Expanded PTFE Braided Packing)FP-550(SC)   (Expanded PTFE Packing W/silicone core)FP-540       (Expanded PTFE Packing W/Lubricant) Code No. (℃) Temperature (Bar) Pressure (m/s) Shaft speedPH range FP-550-212~26825   140180120~14FP-550(SC)16014FP-54016
