Thermally Expandable Microspheres JSYA-EM606 is high-performance physical foaming microspheres, CAS 25103-68-8. It features a tough acrylonitrile copolymer outer shell encapsulating low-boiling hydrocarbon liquid. When subjected to targeted heat during processing, the internal hydrocarbon vaporizes, pressure rises and the soft polymer shell stretches, making microspheres expand sharply and create fine closed-cell foam structure inside PVC, TPR and TPE matrix.

This product delivers stable expa
