There are various types of fluoropolymers.
PTFE is the most common fluoropolymer, accounting for 60-70% of total demand for fluoropolymers.
Fluon® PTFE has the typical characteristics of fluoropolymers.
Finished PTFE products are produced by machining them from a moulding, often produced by compression moulding.
Chemical name: Polytetrafluoroethylene
Fluon® PFA offers the same characteristics as Fluon® PTFE and also offers the advantage of being suitable for producing complicated shapes as it can be melt processed.
Ultra Pure Fluon® PFA, a PFA grade manufactured to be as pure as possible, is also available from Asahi Glass to meet the demands of high-purity applications in the semiconductor industry.
Chemical name: Perfluoroalkoxyethylene
Fluon® ETFE is a copolymer comprising of tetrafluoroethylene and ethylene with outstanding processability, mechanical properties and radiation resistance.
Asahi Glass also offer Fluon® LM-ETFE, which gives improved processability as it is a lower melting point grade.
The Asahi Glass range also includes F-CLEAN® films.
Chemical name: Ethylene-tetrafluoroethylene copolymer
FEP (tetrafluoroethylene-hexafluoropropylene copolymer)
ECTFE (ethylene-chlorotrifluoroethylene copolymer)
