Material : PTFE yarn Size : 3MM ~ 7MM Temperature : 100 deg C + 260 deg C Pressure : 30kg/cm2 PTFE braided packing of multi-filament yarn is braided with stretched and reinforced PTFE fiber, then, fully impregnated with PTFE latex. This packing has good chemical reistance to acid, alkali, solution and other mediums with corrosion, and be applied in wide temperature limit and low friction rate, with good sealing effect in urea amine pump and thick nitric acid plunger pump, the usage life in amine pump with media of grain is more than double of asbestos PTFE packing .
