Unicell MS series is a thermal expandable microsphere. It is composed of polymeric shell and volatile core. The particle size ranges from 10 to 100 μm. When temperature reaches Ts, the shell starts to thin down and expands 40~50 times volumetrically. When temperature reaches over Tmax, the particle may shrink or collapse.

Benefits:

•  Non-formamide/No ammonia release.
•  Fine control over cell size.
•  Wide product spec selection.
