Expandable graphite is a type of flexible graphite and obtained by treating high quality natural scale graphite manufactured by Tianhe.As an ideal and new sealing material(sealant),it is widely

Applied to dynamic and static seal of petroleum, chemical,electricity,astronavigation,automobile,ship and instrument.
Expandable graphite becomes worm like shape after instant treatment in high temperature,and the size of the expandable graphite can expand 100-400 times.The expandable graphite still keeps the property of natural graphite,and still possesses excellent molding plasticity,flexibility and ductibility,and sealability.It is a high quality raw material for all types of graphite plates and sealing member,and can also be used as new casting powder and exothermic agent in metallurgy industry.

Type: 9950250 9980250 9950200 9980200 9550250 9580200 etc.

Specification: particle size 32 mesh 50 mesh 80 mesh 100 mesh –100 mesh –200 mesh –325 mesh.

Expansion rate: 100-400ml/g

Property: good expandability,high temperature resistance,anti-radiation,heat insulation,lubrication,plasticity and chemical stability.

Use: widely applied to the following industries such as steel,metallurgy,petroleum,chemical,machinery,astronavigation,and atomic energy.

Technical index of expandable graphite :

1. Super low sulfur expandable graphite

Specification	Fixed Carbon(%)	Ash Content(%)	Volatile constituent(%)	Expansion Rate (ml/g)	Sulfur content (%)	PH Value	Moisture(%)	Particle Size(%) above the sieve
DL32	90-99.9	≤8.0	≤10	200-400	≤0.03	3-7	≤1.0	≥80
DL50				200-350
DL80				150-250
DL100				100-200

Advantage of this product : sulfur can be reduced to a minimum.

2. Super fine expandable graphite

Specification	Fixed Carbon(%)	Ash Content(%)	Volatile constituent(%)	Expansion Rate (ml/g)	Sulfur content (%)	PH Value	Moisture(%)	Particle Size(%) under the sieve
CX-100	90-99	≤8.0	≤15	30-120	≤2.2	4-7	≤1.0	≥80
CX-200				15-50
CX-325				10-20

Advantage of this product : super fine.
