Product introduction
Expanded microspheres (also known as foamed microspheres) are shells that are made of high molecular weight polymers (acrylonitrile copolymers) with hydrocarbons inside, under heat (100-150°C), the shell softens, hydrocarbons The compound is vaporized by the liquid, so that the shell expands and the shell polymer is replaced.
Characteristic and superiority
When the microspheres are heated to reach the glass transition temperature of the thermoplastic polymer constituting the shell, the shell will soften and become plastic. As the low-boiling core material in the microspheres is heated to generate pressure, the microsphere shell expands. During expansion, the pressure generated by the core material is balanced with the tension of the resin wall material due to stretching.
