PTFE Graphite Filled Gasket

The 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.

Key Features

Exceptional Chemical Resistance

Resistant to over 98% of strong acids, alkalis, and organic solvents, making it ideal for chemical, petrochemical, and pharmaceutical industries.

Permanent Conductivity

Graphite filler provides surface resistance <10⁵ Ω, effectively preventing static accumulation in flammable and explosive environments.

Wide Temperature Range

Operates reliably from -200°C to +260°C, with short-term peaks up to 280°C, ensuring stability in extreme conditions.

Enhanced Seal Durability

Nano-scale dual-phase structure and anti-creep design reduce cold flow by 40%, significantly extending gasket life.

Adaptable Compression & Rebound

Smart compression (12%-18%) and rebound (≥45%) properties adapt to flange deformation, ensuring a secure seal.

Low Friction & Easy Installation

Surface friction coefficient 0.05–0.08 allows fast and easy installation while maintaining tight sealing.

High Pressure Capability

Standard working pressure up to 6.9 MPa, with custom designs up to 20 MPa.

Compliance

FDA/EU 10/2011 certified, suitable for pharmaceutical, food-grade, and sterile applications.

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
