Our low friction graphite sealing materials include flexible sheets, foils, papers, tapes, and strips. Manufactured through chemical intercalation and thermal exfoliation of natural graphite flakes, these products form vermicular structures with approximately 0.003g/cm³ density. The binder-free expanded graphite rolls feature:
Exceptional purity (99.8%+)
Chemical inertness
Radiation resistance
Extreme temperature stability (-200°C to +650°C)
Self-lubricating properties (μ=0.05-0.12)
Gas-tight sealing performance
High compression recovery
Ideal for low-pressure applications requiring minimal friction, these materials can be laminated with metal substrates for enhanced structural integrity.
Low Friction Applications:
High-performance packing rings for rotating equipment
Custom-shaped gaskets with reduced wear characteristics
Graphite-metal composite seals for dynamic systems
High-temperature insulation pads with lubricating properties
Customizable Specifications:
Roll Dimensions:
Width: 1000mm / 1500mm (custom widths available)
Length: 30m / 50m / 80m
Sheet Size: 1000x1000mm / 1500x1500mm
Thickness Range: 0.15-5.0mm
Density: 0.8-1.25g/cm³
Friction Coefficient: 0.05-0.12 (depending on formulation)
Engineered for low friction environments, our graphite sealing materials provide reliable performance in pumps, valves, and rotating machinery while maintaining dimensional stability.
