Title:
POLYTETRAFLUOROETHYLENE FILM FOR ELECTRONIC COMPONENTS
Document Type and Number:
Japanese Patent JP2019192749
Kind Code:
A
Abstract:
To provide a polytetrafluoroethylene (PTFE) film for electronic components that suppresses moisture permeation and transpiration of an electrolyte used in electronic components.SOLUTION: The PTFE film for electronic components is used for a sealing plate 4 of an aluminum electrolytic capacitor having rubber 11, a phenol resin film 12, a polypropylene resin film 13, and a PTFE film 14. Density of the PTFE film is 1.40 g/cmor more. Air permeability resistance is 3000 sec or more. Liquid pressure resistance is preferably 0.8 MPa or more. More preferably, a film thickness is 10 to 1000 μm.SELECTED DRAWING: Figure 2
