Spherical Silica

MEGASIL™ SS

Spherical Silica powders are used in the production of Epoxy Moulding Compounds (EMCs) and green EMCs (halogen-free, antimony-free), which are thermosetting materials encapsulating and protecting semiconductor devices (e.g., memory integrated circuits (ICs) tied to 5G and IoT devices) from physical and environmental damage. Applications: consumer, automotive, and industrial electronics.
