Product Description

Expandable graphite is a high-quality natural phosphorus flake graphite produced by our company, which is a flexible graphite product obtained through special modification treatment. It is an ideal new sealing material and widely used in dynamic and static sealing in industries such as petroleum, chemical, electrical, aviation, automotive, shipbuilding, and instrumentation.
 
Expandable graphite undergoes high-temperature instantaneous treatment, transforming into a worm like flake with a volume that can expand 100-400 times. This type of expanded graphite still retains the properties of natural graphite and has good plasticity, flexibility, ductility, and sealing properties. It is a high-quality raw material for various graphite sheets and seals, and can also be used as a new type of protective slag and heating agent in the metallurgical industry.
Variety: 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
Performance: It has good expandability, and the finished product has high temperature resistance, radiation resistance, insulation, lubrication, plasticity, and chemical stability
Usage: Widely used in industrial sectors such as steel, metallurgy, petroleum, chemical industry, machinery, aerospace, and atomic energy.

Technical indicators of expandable graphite:
1. Ultra low sulfur expandable graphite

specifications	Fixed carbon (%)	Ash content (%)	Volatile matter (%)	Expansion rate (ml/g)	Sulfur content (%)	PH value	Moisture content (%)	Particle size (%)  Sieved material
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

The advantage of this product is that the sulfur content can be controlled within the minimum range.




2. Ultra fine expandable graphite

specifications	Fixed carbon (%)	Ash content (%)	Volatile matter (%)	Expansion rate (ml/g)	Sulfur content (%)	PH value	Moisture content (%)	Particle size (%)  Sieved material
CX-100	90-99	≤ 8.0	≤ 15	30-120	≤ 2.2	4-7	≤ 1.0	≥ 80
CX-200				15-50
CX-325				10-20

The advantage of this product is: ultra-fine.

3. Ordinary expandable graphite

specifications	Fixed carbon (%)	Ash content (%)	Volatile matter (%)	Expansion rate (ml/g)	Sulfur content (%)		PH value	Moisture content (%)	Particle size (%)  on sieve
					Before expansion (%)	After expansion (ppm)
Kp32	90-99.9	≤ 8.0	≤ 12	200-400	≤ 2.2	≤ 1500	3-7	≤ 1.0	≥ 80
Kp50				200-350
Kp80				150-250
