Highest puricity graphite filament yarn, dry and without impregnation
Characteristics
- Elastic and wear resistant, low coefficient of friction
- Excellent in applications with temperature changes due to graphite and steel having a similar coefficient of expansion
- Recommended as bullring for expanded graphite packing like A 44
- When used as pump packing shaft hardness HRC 45 is recommended
