Product description 

FST Grafolan consists of graphite yarn which is created through an energy-intensive thermal transformation process. It features high chemical resistance and temperature stability. An added lubricant ensures good running-in behaviour at all speeds.

FST Grafolan is used in many areas of chemistry – in pumps, agitators and paddle dryers – as well as in feed water pumps for energy production. Compression-moulded rings from FST Grafolan 6576 (without additional lubricant) are supplied.
