Products Description
 

DIN-Compliant Industrial Graphite Sheets

Product Overview

DIN-standard industrial graphite sheets, along with graphite foil, paper, tape, and strip, are advanced sealing materials manufactured from natural graphite flakes via a two-stage process: chemical intercalation and thermal expansion. This produces exfoliated graphite structures with a bulk density of approximately 0.003g/cc. The expanded graphite is then compressed into rolls or sheets without binders, ensuring a purity level exceeding 99.8% and compliance with DIN EN 13555 for sealing applications.

Key Features Meeting DIN Requirements

  1. Material Purity
    • Meets DIN 52900 standards for ash content (<0.2%) and sulfur content (<0.1%).
    • Free of halogenated compounds, aligning with DIN EN 61249-2-21 for electronic applications.
  2. Thermo-Mechanical Properties
    • Thermal stability from -200°C to +3000°C (DIN EN 1356 standard).
    • Compressive strength of 50-80 MPa (DIN EN 13555) with <3% creep relaxation under 100 bar pressure.
  3. Dimensional Accuracy
    • Width tolerance: ±0.5mm for 1000mm/1500mm rolls (DIN EN 13555).
    • Thickness uniformity: ±5% for 0.15-5mm sheets (DIN EN ISO 4784).

Applications in DIN-Compliant Systems

  1. Flange Sealing
    • Used in ASME B16.5/DIN EN 1092-1 flange connections, providing leak-tight seals for gas, liquid, and slurry pipelines.
    • Composite variants with stainless steel inserts meet DIN EN 15149-2 for pressure equipment.
  2. Valve & Pump Seals
    • Graphite packing rings for valves comply with DIN 3352, ensuring reliability in oil refineries and chemical plants.
    • Self-lubricating properties reduce friction in pumps adhering to DIN 24256 standards.
  3. High-Temperature Insulation
    • Thick plates (1.0-5mm) used in furnace doors and heat exchangers, meeting DIN 1709 for thermal insulation.

Technical Specifications

  • Sizes:
    • Rolls: 1000mm/1500mm width, 30m/50m/80m length.
    • Sheets: 1000mm x 1500mm, thicknesses 0.15-5mm.
  • Density: 0.8-1.25g/cm³ (customizable per DIN EN 13555).
  • Surface Finish: Smooth (<Ra 0.8μm) or textured for specific grip requirements (DIN 4768).

Compliance & Testing

  • Certified to DIN EN ISO 9001:2015 and DIN EN 14576 for environmental management.
  • Tested by TÜV for flame resistance (DIN 4102 B1) and chemical compatibility (DIN 53438).
  • Available with full traceability documentation in compliance with DIN EN 10204 3.1B.

Why Choose Our DIN-Compliant Graphite Sheets?
