What are PFA?

PFA or perfluoroalkoxy alkanes are fluoropolymers,which have been developed based on polytetrafluoroethylene (PTFE). In lab jargon PFA coating is often falsely referred "Teflon coating", implying that the actual coat would be PTFE, which looks very similar. Compared to PTFE, PFA have better anti-stick properties, higher chemical resistance on expense of a lesser scratch resistance. PFA are preferred when extended service is required in hostile environments involving chemical, thermal, and mechanical stress. (see Wikipedia)
