Surface protective film

A surface protective film includes a structure in which a fluorine resin having a perfluoroalkylene ether structure in a main chain is crosslinking polymerized, wherein a storage elastic modulus E′ is in the range of 10 MPa to 1000 MPa at a temperature which is 40 K higher than a dynamic glass trans...

Zusammenfassung:A surface protective film includes a structure in which a fluorine resin having a perfluoroalkylene ether structure in a main chain is crosslinking polymerized, wherein a storage elastic modulus E′ is in the range of 10 MPa to 1000 MPa at a temperature which is 40 K higher than a dynamic glass transition temperature Tg in dynamic viscoelasticity measurement at a measurement frequency of 10 Hz.
