More evolved CO 2 gas leads to the bubbles in FEP films during thermal. 3M™ Dyneon™ Fluoroplastic Granules FEP 6307Z is a fully fluorinated copolymer used in extrusion, injection molding and transfer molding processes for the wire and cable and chemical process industries (CPI). 0-3. It has excellent chemical stability and excellent non-stick properties. Like FEP, it is melt processible. The deposition time was the same for all PED and PLD processes, corresponding to 5000 pulses at a 5 Hz pulse repetition rate.
