Spherical Silica

Spherical Silica

Currently, silica is used as a filler in many electrical and electronic materials, including encapsulants. Silica can be irregularly shaped or spherical, and the main applications of spherical silica include underfill and anti-blocking materials.

Main features

● Various advantages such as improved fluidity, high filling, and improved wear resistance can be obtained by spherical former.
● It is possible to respond to various particle size distributions that match the customer’s requirements.
