the reserved atbc in the wpu film also acts as an effective plasticizer and lubricant so that the wpu film can be quickly peeled off from pet. the lowest t-peel strength of 1.3 n m −1 on pet is achieved for the wpu film with a high tensile strength of 15.8 mpa and a medium elongation at break of 237%. the wpu films have tunable stickiness.
