摘要: Provided is a surface protection sheet that is less susceptible to breaking and tearing caused by adherend processing and can be easily removed from the adherend. The surface protection sheet comprises a substrate and a PSA layer placed on one face of the substrate. The base polymer of the PSA layer has a glass transition temperature of −50° C. or higher. The surface protection sheet has at least 200% elongation at break in both the machine direction and the transverse direction.

摘要: The present invention refers to a thermally debondable tape having a base adhesive layer and at least one thermally releasable adhesive layer including an adhesive and thermally expandable particles. The debondability even after long term storage or use shall be enhanced. In this regard the base adhesive layer has a lower adhesion at expansion temperature of the thermally expandable particles than at room temperature.
