Title:
REWORKABLE DOUBLE-SIDED FOAM TAPE, REWORKING METHOD, AND PREPARATION METHOD
Document Type and Number:
WIPO Patent Application WO/2024/092861
Kind Code:
A1
Abstract:
Disclosed is a reworkable double-sided foam tape, comprising: a tearing layer, having a first surface and a second surface opposite to each other in a thickness direction; two foam layers, respectively arranged on the first surface and the second surface of the tearing layer; two pressure sensitive adhesive layers, respectively arranged on the surfaces of the foam layers facing away from the tearing layer, wherein the tearing layer comprises a plurality of tearing strips, the lengths of the plurality of tearing strips extend in a first direction, adjacent tearing strips are arranged side by side, and adjacent tearing strips are spaced apart from each other and/or connected by means of a perforated line. The reworkable double-sided foam tape has a reasonable lamination structure; the tearing layer is configured to be strip-shaped tearing strips extending in the same direction, a gap is formed between every two adjacent tearing strips for facilitating tearing or tearing is achieved by means of the perforated line provided between every two adjacent tearing strips, and then the tearing strips are separated, so that the foam layers on the two surfaces of the tearing layer are separated, and the reworking purpose is achieved; the workload of manually dividing the foam layers in the reworking operation is reduced, the operation is simple and convenient, and the efficiency is high.
