PTFE Filament Packing is made of sintered, highly stretched PTFE multifilament yarns reinforced with secondary PTFE emulsion impregnation. It features Structural Density, excellent Vibration Damping, 30-50% longer Dynamic Seal Lifespan compared to traditional Pure PTFE Packing.
PTFE Filament packing is ideal for replacing traditional asbestos-based or aramid braided packing, enhancing sealing reliability while complying with environmental regulations.

PACKAGE: In coils of 5 or 10 kg, other weights on request. A box for each coil, 20 kgs per carton.
Structural Design: High-density braiding, compact cross-section, excellent dimensional stability, strong resistance to compression and extrusion
Chemical Resistance: Resistant to all chemicals except molten uranium salts, including strong acids, alkalis, and organic solvents.
Eco-Safety: 100% asbestos-free, extremely low water absorption (<0.01%), clean and non-contaminating.
Friction Control: PTFE dispersion layer significantly reduces friction, minimizing wear and leakage risks
Valve Sealing: Globe valves, needle valves, safety injection system valves
Pump System: Low-speed shaft pumps, plunger pumps
Chemical Processing: Acid/alkali fluid transfer, reactor agitator shafts
Precision Control: Contamination-sensitive environments (e.g., pharmaceutical, food-grade equipment)
