Our flexible graphite materials—comprising sheets, foil, paper, tape, and strips—are produced using proprietary chemical exfoliation and thermal expansion processes. Natural graphite flakes are transformed into worm - like structures with a bulk density of 0.003g/cc, then rolled into binder - free coils. This results in materials with 99.8%+ purity, engineered for precise OEM gasket manufacturing.
Full - Cycle OEM Capabilities
Custom Design & Prototyping
CAD/CAM engineering for complex gasket geometries (spiral - wound, corrugated, cut - to - size)
Rapid prototyping via laser/waterjet cutting (tolerances ±0.05mm)
Material Hybridization
Composite solutions combining graphite with metals (stainless steel, tinplate) or polymers (PTFE)
Custom density ranges (0.8–1.5g/cm³) for specific pressure/temperature requirements
Mass Production Efficiency
High - speed rolling lines producing 500+ meters of coils daily
Automated die - cutting for consistent gasket dimensions (widths 1000mm/1500mm)
Key Performance Features
Chemical Resistance: Withstands acids (H₂SO₄), alkalis (NaOH), and organic solvents (e.g., methyl ethyl ketone)
Thermal Stability: Operates from - 200°C (cryogenic) to +1600°C (high - temperature furnaces)
Mechanical Properties: Compressive strength up to 70 MPa, elongation at break 8 - 12%
Quality Assurance System
ISO 9001:2015 certified manufacturing processes
In - line testing for:
Density (ASTM D792)
Tensile strength (ASTM D638)
Gas permeability (ASTM D1434)
100% visual inspection for surface defects
