| abstract |
The present invention is a polyolefin-based resin foam sheet having an areal density of 5 g/m 2 or more and 400 g/m 2 or less, and a thermogravimetric measured at a heating rate of 10° C./min and a measurement temperature of 23° C. to 550° C. In the analysis, the time (t) it took for the weight to decrease from 90% by mass to 10% by mass was 9 minutes or more. According to the present invention, it is possible to provide a polyolefin-based resin foam sheet having high flame retardancy while maintaining lightness. |
