Carbon-filament yarn with high-temperature graphite impregnation.
The high-temperature graphite impregnation raises the cross-section density and acts as a stable pressure cushion for the carbon fibres
Elastic, doesn’t wear and offers valve stem protection
Excellent with temperature changes, as carbon and steel have a similar thermal expansion coefficient
Excellent suitability for bullrings (anti-extrusion rings) in combination with expanded graphite packing like STYLE 350
