Abstract:
A production method for heat-expandable microspheres, which have high expanding ratio and are thermally expanded into hollow particulates having excellent repeated-compression durability, and application thereof are provided. The method produces heat-expandable microspheres a shell of thermoplastic resin and a blowing agent being encapsulated therein and having a boiling point not higher than the softening point of the thermoplastic resin.
