The protective film is a viscoelastic polymer

Principle of protective film adhesive (glue): protective film is a viscoelastic polymer

Film: The adhesive layer of the protective film can be in close contact with the surface of the adherend, and flows into the groove on the adhered surface as much as possible, so that the effective contact area of the protective film is increased.

Tear film: All adhesive layers have high peel resistance. The higher the peeling speed of the protective film, the higher the peel strength of the pressure-sensitive adhesive.


Protective film adhesion performance (stickiness): initial adhesion <adhesion <cohesion <adhesion base force
