    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?

    • Precision Engineering: Laser-cutting ensures ±0.1mm dimensional accuracy for complex shapes.
    • Cost Efficiency: Reduces maintenance costs by 40% compared to traditional materials in continuous operation.
    • Global Support: On-site installation guidance provided by engineers certified to DIN 66023.

    Engineered to meet the most rigorous European industrial standards for sealing and insulation.
