Product Description

Products Description
 

ISO 9001 - Certified Graphite Gasket Manufacturing Solutions

Product Overview

Engineered from natural graphite flakes via a proprietary chemical intercalation and thermal expansion process, our flexible graphite materials—including sheets, foil, paper, tape, and strips—undergo rigorous quality control adhering to ISO 9001:2015 standards. The production process creates exfoliated graphite worms with a bulk density of 0.003g/cc, which are cold - rolled into binder - free coils. This results in materials with ≥99.8% purity and exceptional performance characteristics validated by third - party audits.

ISO 9001 Quality System Integration

  1. Material Traceability
    • All raw materials are sourced from certified suppliers and tracked through blockchain technology for 100% product traceability.
    • Each batch undergoes XRF analysis to verify chemical composition compliance.
  2. Process Control
    • Automated rolling mills maintain thickness tolerances within ±0.02mm for coils and ±0.1mm for plates.
    • Statistical process control (SPC) charts monitor critical parameters like compression ratio and expansion temperature.
  3. Final Inspection
    • 100% visual inspection for surface defects
    • Random sampling for physical testing (ASTM D696 for thermal expansion, ASTM F38 for stress relaxation)

Key Advantages for ISO - Compliant Clients

  1. Performance Consistency
    • Density customizable between 0.8 - 1.25g/cm³ with batch - to - batch variation ≤5%
    • Compressive strength exceeding 50 MPa (ASTM F36 tested)
  2. Chemical & Thermal Stability
    • Resists acids (pH 1 - 3), alkalis (pH 11 - 14), and organic solvents
    • Operates reliably from cryogenic (-200°C) to 1650°C in oxidizing environments
  3. Regulatory Compliance
    • RoHS/REACH compliant with full SVHC declarations
    • FDA - compliant grades available for food/pharmaceutical applications
