What are the excellent properties of flexible graphite?
Thread Content
Flexible graphite material (also known as expanded graphite) belongs to pure graphite materials and contains no adhesives or bonding agents of its own. Therefore, its performance is not limited by the bonding material, but is determined solely by the graphite itself. 1) Good heat resistance. Flexible graphite materials possess the temperature resistance of ordinary natural graphite. The operating temperature range is from -200 to 1600°C in non-oxidizing media, and it can also be used below 400°C in oxidizing media. 2) Excellent corrosion resistance. Flexible graphite exhibits excellent corrosion resistance, maintaining good chemical stability against common chemical solvents, petroleum products, esters, steam, and reducing agents. 3) Other excellent properties. Such as good flexibility and resilience, good airtightness, radiation resistance, and self-lubrication. Therefore, flexible graphite is widely used for both dynamic and static sealing. For manufacturing auxiliary sealing rings used in high-temperature mechanical seals, flexible graphite is the best material. Due to its poor strength and tendency to break, care should be taken when using it.
The excellent properties of flexible graphite include high-temperature resistance, corrosion resistance, good flexibility and resilience, airtightness, radiation resistance, and self-lubrication. However, its strength is poor and it is prone to breaking. .
