Expandable graphite products using high quality flaky graphite as raw material, and after special chemical process. Expandable graphite are instantaneous high temperature treatment, flake becoming to vermicular , volume expand 100~400times, this expandable graphite still keep the performance of nature graphite, and having good mold plasticity, flexible scalability and sealing ability, it is the good sealing material of graphite plates, also can be used for the metallurgical industry protection slag, flame retardant material.
Features of Expandable graphite：

Expandable graphite are instantaneous high temperature treatment, flake becoming to vermicular , volume expand 100~400times, this expandable graphite still keep the performance of nature graphite, and having good mold plasticity, flexible scalability and sealing ability, it is the good sealing material of graphite plates, also can be used for the metallurgical industry protection slag, flame retardant material.
Application of Expandable graphite：
1.Additives of metallurgical industry.
2.Material of flexible graphite paper.
3.Battery adsorbent material.
4.Additives of lubricant.
5. Additives of fire-extinguishing agent.
1)
Expandable graphite should be stored in a dry, ventilated place where
there is no other sources of pollution (recommended: temperature ≤ 45 °
C, humidity ≤ 85%);
2) Expandable graphite should be neatly stacked, and the production batch number, date and other signs should be clearly identified;
3) Expandable graphite
should be carefully Handled during transportation to avoid the damage
of the packaging; products that leak out of the package must not be
returned to the box.
Technical Parameter of Expandable graphite：
| Specification | Carbon | Volatile | moisture | exponsion degree | PH | Particle Size |
| Result | 90%-99.9% | ≤13 | ≤2.5 | 130-400 | 3-6 | ≥80 |
