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.
