EXPANDABLE GRPAHITE    H.S. CODE :3824999940

                                       CAS Number: 12777-87-6

                                       Standard : GB 10698- 89

1. Introduction :


Expandable graphite is a kind of flexible graphite product obtained from high-quality natural flake graphite produced by our company through special modification. It is an ideal new sealing material.


It is widely used in dynamic and static sealing in petroleum, chemical industry, electric power industry, aviation, automobile, ship, instrument and other industries.


After instantaneous treatment at high temperature, the expandable graphite becomes vermicular in scale shape, and the volume can expand 100-400 times.


This expandable graphite still maintains the properties of natural graphite, and has good molding plasticity, flexibility, ductility and sealing.


It is a high-quality raw material for various graphite plates and seals. It can also be used as a new protective slag and heating agent in the metallurgical industry.

4. Application :


  •    Sealing materials: compared with traditional sealing materials such as asbestos rubber, flexible graphite prepared from expanded graphite has good plasticity, resilience and lubricity, and is light, conductive, heat conductive, high temperature resistant and acid and alkali resistant. It is used in aerospace, machinery, electronics, nuclear energy, petrochemical, electric power, shipbuilding, smelting and other industries;

  •   Environmental protection and biomedicine: expanded graphite obtained by high temperature expansion has rich pore structure, good adsorption performance, lipophilic and hydrophobic, good chemical stability and renewable reuse;

  •  High energy battery materials: use the free energy change of expandable graphite interlayer reaction to convert into electrical energy, which is usually used as negative electrode in batteries;

  •  Flame retardant and fireproof materials

  •  Sealing strip: used for fireproof doors, fireproof glass windows, etc;

  •  Fireproof bag, plastic fireproof plugging material and fire ring: used to seal building pipes, cables, wires, gas and gas pipes;

  •  Flame retardant and antistatic coating;

  •  Wall insulation board;

  •  Foaming agent;

  •  Plastic flame retardant .



5. Performance :

 

  • Good Expansibility

  • High Temperature resistance

  • Radiation Protection

  • Heat Insulation

  • Lubrication

  • Plasticity and Chemical Stability
