Metal Casting:
NICKUNJ Flexible Graphite NCK995® protects graphite moulds and ingot moulds against penetration by certain metals and alloys; it stops the rapid deterioration of expensive

Dynamic seals:  stuffing box sealing rings for: pumps, valves, chemical equipment.
Rotating rings
Valve seats


Static seals:
flange seals
gaskets for exhaust gas manfolds
cylinder head gaskets
pump casing gaskets

Glass Industry: Is not affected by molten or semi - molten glass. It does not scratch moulded products whilst they are still hot, nor does it cause local cooling when in contact with them (no glazing). It may therefore be used for gland packing of push rods, support plates and for replacing asbestos base material with a totally innocuous product.


Other applications:
In operations involving hot compression and in particular in sintering, the thinnest NCK995® may be used as a lining to facilitate removal from the mould. In soldering and brazing operations, particularly on delicate components, which is not affected by molten metals, may be used to limit the work zone and so protect adjacent areas from the risk of damage.
