High-Temp Expandable Microspheres JSYA-EM501 is high heat resistant thermally expandable microspheres with CAS 25103-68-8. It adopts reinforced thermoplastic copolymer shell, encapsulating low boiling-point hydrocarbon inside. The foaming activation temperature range is 160–180°C. When heated within this high-temperature window, the internal hydrocarbon vaporizes, pressure increases continuously and the tough polymer shell expands to form fine, independent closed-cell foam structure inside engin
