PURPOSE:An expanded plate providing a panel having improved molding properties, good hardness, heat insulating properties, etc., obtained by using a expanded plate of thermoplastic resin having fixed ranges of surface hardness and a remaining blowing agent. CONSTITUTION:An expanded plate of thermoplastic resin having <=50-80 surface hardness, and 3-7wt% remaining blowing agent amount before uneven molding is used. A styrenic resin having 5-20g/10min melt flow rate is used as the thermoplastic resin. The expanded plate has preferably about 5-15mm thickness and 10-20 times expansion magnification. |
