Title:
POLYOLEFIN RESIN FOAM, PRODUCTION METHOD THEREFOR, AND ADHESIVE TAPE
Document Type and Number:
WIPO Patent Application WO/2019/073873
Kind Code:
A1
Abstract:
This invention addresses the problem of providing a polyolefin resin foam sheet suitable for use as a sealing substrate that exhibits both flexibility and heat resistance regardless of having a thin thickness, and an adhesive tape in which said polyolefin resin foam sheet is used. The invention addresses this problem by providing a polyolefin resin foam that: comprises a thermoplastic elastomer; exhibits endothermic peaks at least at 110–143°C, inclusive, and at 153°C or higher in differential scanning calorimetry (DSC); and includes a thermoplastic elastomer resin that institutes 30–60mass% of 100mass% of the polyolefin resin.
