Dalau Dalcon 021 75% Virgin PTFE, 25% Carbon Coke

Applications & Industries: General: Carbon / Coke (soft) filler is good in dry running conditions, adds to the creep resistance, increases the hardness and raises the thermal conductivity of PTFE; Carbon / Coke (soft) compounds have good wear properties, but has low tool wear during machining, thus allowing machining to very close tolerances; Carbon / Coke (soft) compounds have some electrical conductivity and are therefore antistatic; and Carbon filled compounds when combined with graphite, have excellent wear properties. The combination of the above properties makes carbon / graphite compounds the preferred material for non - lubricated piston rings. Chemical: Dynamic & shaft seals and Seals & gaskets. Flat gaskets are used to seal flanges in pipelines.Construction: Bridge bearings. Slide bearings.Engineering: Anti - friction bearing cages & bearing plates; Bearings, bushes, shaft bearings / seals (in combustion engines); Film bearings. Multi - layer composite bearings. Fabric bearings; Laboratory equipment. Measuring & control technology; Pipe supports. Expansion bellows. Glandless valves & pumps, valve seats; Piston rings in hydraulic systems and compressors; and Piston rod packings used in compressor plunger pumps & valves.CHEMICAL RESISTANCE: The strength of the carbon - fluorine bond and the shielding of the carbon chains by the fluorine atoms result in a chemical inertness which is virtually universal, except alkali metals, fluorine under certain conditions, some fluorine compounds & halogen gases at elevated temperatures. Carbon / Coke is a good inert filler, except in oxidising environments where glass performs better. Resistant to hydrofluoric acid.Information provided by Dalau
