Guarniflon PFA Perfluoroalkoxy Polymer
PFA
Guarniflon
产品说明：
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.
