Non-reinforced graphite sheets
Graphite sheets Hexaflex™ type N are manufactured using a whole range of Hexaflex™ graphite foils which are characterized by low content of sulphur, chlorine and other halogens with further processing to the form of sheets of the required thickness. Sheets efficiently withstand temperature changes and most chemical medias.
Homogeneous graphite sheets Hexaflex™ are best choice when complicated design or immediate reparation works are required as well as usage in sensitive flange materials.
APPLICATIONS
- Filler material for corrugated and kammprofile gaskets;
- Chemical, petrochemical industries, gas supply;
- Shipbuilding; metal production and processing.
MAIN FEATURES AND PROPERTIES
- Excellent chemical and thermal resistance;
- Zero sulphur and halogen content;
- Conformity to irregular flange sealing surfaces;
