STRETCHED THERMOPLASTIC RESIN FOAM SHEET AND PROCESS FOR PRODUCTION OF THE SAME

摘要

The invention provides a stretched thermoplastic resin foam sheet which exhibits excellent softness even in a state compressed to a thickness as extremely small as about 0.05mm and a process for the production of the same. The invention relates to a stretched thermoplastic resin foam sheet which is produced by stretching a thermoplastic foam sheet and which is characterized by exhibiting a compressive strength of 1 to 500kPa as determined according to JIS K6767 in a state compressed thicknesswise to 0.05mm. The stretched thermoplastic resin foam sheet exhibits excellent softness even in a state compressed to a thickness as extremely small as about 0.05mm and is suitable for the sealing material for small-sized electronic appliances such as cellular phone.
