Title:
PERVAPORATION MEMBRANE
Document Type and Number:
WIPO Patent Application WO/2024/070574
Kind Code:
A1
Abstract:
The present invention provides a pervaporation membrane adapted for the suppression of peeling of the separation-functional layer from the porous support when the pervaporation membrane is unwound from a wound body of the pervaporation membrane. A pervaporation membrane according to the present invention comprises: a separation-functional layer containing a silicone resin; and a porous support that supports the separation-functional layer. The peel strength of the pervaporation membrane, as measured using the following test, is at least 0.15 N/20 mm. Test: A test specimen is prepared by cutting the pervaporation membrane to width 20 mm x length 150 mm. Using this test specimen, the separation-functional layer is peeled from the porous support at a peeling angle of 180° and a pulling rate of 300 mm/min.
