Graphite PTFE Packing with Aramid Fiber Corner is a high-performance composite sealing material. It utilizes PTFE-impregnated aramid fibers as corner reinforcement, combined with high-quality graphite PTFE(black PTFE) yarn as the main sealing body, processed through a specialized braiding technique. This structure retains the high strength of aramid fibers while integrating the low friction, corrosion resistance, and excellent thermal conductivity of graphite PTFE, making it ideal for dynamic sealing in high-speed, high-pressure, and highly corrosive conditions
