1.sheat-resistant range under the oxygen-free environment 2.chemicaly stable under conditions of high temperature
After a special chemical treatment in high temperature can be instantaneously inflated into a wormlike natural crystalline graphite.
Property: With good expansion, unconsolidated porous, oxygen isolation under a wide range of temperature, in-between the -200~3000°C, chemically stable under conditions of high temperature and high pressure or radiation.
Specification: particle size 32 mesh 50 mesh 80 mesh 100 mesh –100 mesh –200 mesh –325 mesh.Expansion rate: 100-400ml/g.
Application: It can be used as advanced sealing materials, fire retardant materials, expansion worm powder can be used in lithium battery materials, insulation and insulation material.
