1, Poly FEP structural features:
F- 46 B Acrylic resin and PTFE, As is a fully fluorinated structure, Unlike some of the main chain PTFE fluorine atoms are trifluoromethyl (- CF3) replaced by the structural formula is as follows:
Thus, F- 46 resin and PTFE fluorocarbon though by the elements, Carbon chain surrounded completely surrounded by fluorine atoms, But the F- 46 of its macromolecular chain on the main branch and side chain. This structural differences in the long- Term stress for the material under the upper limit temperature range of view, No significant impact, F- 46's maximum temperature of 200 ℃, While the maximum use of Teflon temperature 260 ℃. However, This structural difference, While filling the F- 46 resin has a very defined melting point, And can be generally forming thermoplastic processing methods, So that processing technology greatly simplified. This is a PTFE are not available. This is hexafluoropropylene PTFE with the main purpose.
2, Poly FEP performance
F- 46 in the hexafluoropropylene content of the performance of the copolymer there is a certain impact. The current production of F- 46 resin hexafluoropropylene content, Usually 14% - 25% (mass fraction) around.
