Expandable Microspheres for Auto Interior JSYA-EM501 is high heat-resistant thermally expandable microspheres with CAS 25103-68-8. It features reinforced thermoplastic copolymer shell encapsulating low-boiling hydrocarbon inside. Under high-temperature extrusion or injection molding for automotive polymers, the inner hydrocarbon vaporizes, internal pressure rises, and the tough shell expands to create tiny, independent closed-cell foam structure in TPO and TPV matrix.
