Thermally Expandable Graphite (TEG)

Thermally Expandable Graphite (TEG) is a material derived from natural graphite through a patented intercalation compound treatment. This process imbues graphite with thermal expansion properties, allowing it to expand significantly when heated to temperatures around 200°C.

Features and Benefits:

• Expansion begins between 200 and 220°C, with approximately 200-fold expansion upon heating.
• Easily compression-moulded without binders.
• Acts as a flame retardant in combustible materials like rubber and resin.
• Non-halogen, preventing emission of hazardous gases during combustion.

Applications:

• Seal components (gaskets and packing)
• Flame retardants (for rubber, resin, and construction materials)
• Thermally conductive materials (heat dissipation sheets and electronic components)

At Bisley, we have different TEG grades available to meet specific needs, ranging from standard products to those tailored for high-temperature environments or ultra-low ash content.
