Its low C/F ratio and its insaturations allow achieving the highest aspect ratios in etching. Sifren® 46 (C4F6 or Hexafluoro-1,3-butadiene) is an unsaturated fluorocarbon with an alternating double bond.

Halocarbon PCTFE Technology: Low-Molecular Weight Oligomers

WebPolychlorotrifluoroethylene ( PCTFE or PTFCE) is a thermoplastic chloro fluoropolymer with the molecular formula (CF 2 CClF) n, where n is the number of monomer units in the polymer molecule. It is similar to polytetrafluoroethene (PTFE), except that it is a homopolymer of the monomer chlorotrifluoroethylene (CTFE) instead of tetrafluoroethene.
