El Chunhuan Group PTFE Graphite Filled Gasket is a high-performance sealing solution designed for demanding industrial environments. Combining the exceptional chemical resistance of virgin PTFE with the conductivity and compressibility of graphite, it delivers reliable sealing in corrosive, high-purity, and electrically sensitive applications.
Resistant to over 98% of strong acids, alkalis, and organic solvents, making it ideal for chemical, petrochemical, and pharmaceutical industries.
Graphite filler provides surface resistance <10⁵ Ω, effectively preventing static accumulation in flammable and explosive environments.
Operates reliably from -200°C to +260°C, with short-term peaks up to 280°C, ensuring stability in extreme conditions.
Nano-scale dual-phase structure and anti-creep design reduce cold flow by 40%, significantly extending gasket life.
Smart compression (12%-18%) and rebound (≥45%) properties adapt to flange deformation, ensuring a secure seal.
Surface friction coefficient 0.05–0.08 allows fast and easy installation while maintaining tight sealing.
Standard working pressure up to 6.9 MPa, with custom designs up to 20 MPa.
FDA/EU 10/2011 certified, suitable for pharmaceutical, food-grade, and sterile applications.
Pipelines, valves, and flanges in chemical, petrochemical, and pharmaceutical industries
Strongly corrosive and electrically sensitive environments
Chlor-alkali reactors, LNG ultra-low temperature pipelines, and semiconductor specialty gas systems
Bioreactors and sterile filling lines requiring zero-leak sealing
