Polypropylene resin composition foam |
| abstract |
(57) [Problem] To provide a polypropylene resin foam which is lightweight, has a high closed cell ratio, has a fine cell diameter, and has a beautiful appearance. SOLUTION: The content of the polypropylene resin is 50% by weight or more, and the melt tension at break at 180 ° C. is 2%. 0 g or more, and the take-off speed at break is 5 m / mi n is a foam obtained by extrusion foaming a polypropylene resin having a shear viscosity of 1000 Pa · sec or more. |
