PFA

PFA

Fluorinated thermoplastic material, offers the advantages of being thermo-processed whilst at the same time having the properties of PTFE, with excellent chemical and mechanical resistance for applications up to 260°C.
Thanks to its fluidity during the processing, the final products in PFA – especially the skived film - are absolutely porous- free, hence very suitable for electrical applications.
