Edge-protection tape
First Claim
1. Adhesive tape for the protection of glass edges, comprising, in sequence directed towards the substrate to be covered,a hard phase which is a backing layer, anda soft phase having a polymer basis selected from polyolefins and polyacrylates, and mixtures thereof, said soft phase comprising a polymer foam,where the thickness of the hard phase is ≦
- 150 μ
m, the thickness of the soft phase is ≧
200 μ
m and the ratio of the thickness of the soft phase to the thickness of the hard phase is ≧
4,wherein the soft phase comprises a first pressure-sensitive adhesive layer arranged above the polymer foam and a second pressure-sensitive adhesive layer arranged below the polymer foam.

Abstract
A self-adhesive edge-protection tape is intended to improve the protective effect for glass edges. This is achieved by providing an adhesive tape which comprises, in sequence directed towards the substrate to be covered, a backing layer (hard phase) and a soft phase comprising a polymer foam, a viscoelastic composition and/or an elastomeric composition, where the thickness of the hard phase is ≦150 μm, the thickness of the soft phase is ≧200 μm and the ratio of the thickness of the soft phase to the thickness of the hard phase is ≧4. The invention also relates to a solar module which comprises an adhesive tape according to the invention adhesive-bonded around at least one portion of the edges thereof, and the use of the claimed adhesive tape for the protection of edges of a solar module.
