Surface protective sheet |
| abstract |
(Sludge penetration) to the surface to be protected of the workpiece from the interval formed by the workpiece being cut off during the back grinding process of the workpiece. A surface protective sheet capable of preventing contamination of a surface to be protected of a work. A surface protective sheet having a pressure-sensitive adhesive layer on a substrate, the surface protective sheet satisfying the following requirements (a) to (d). (a) the Young's modulus of the substrate is 450 MPa or more. (b) the pressure-sensitive adhesive layer has a storage elastic modulus at 25 DEG C of not less than 0.10 MPa. (c) The pressure-sensitive adhesive layer has a storage elastic modulus at 50 캜 of 0.20 MPa or less. (d) the thickness of the pressure-sensitive adhesive layer is 30 占 퐉 or more. |
