Electronics
Electronics quartz is a fine, high-purity micronised quartz used as a filler in the encapsulation and potting resins of electronic components. In electronic epoxy and casting compounds, quartz improves thermal stability, dimensional balance and electrical insulation properties. High-purity micronised quartz (typical SiO₂ 99.8%) delivers consistent performance in electronic filler applications.
How to Choose Electronic Filler Quartz?
Several criteria define the right electronic filler quartz. Grain size and distribution determine the flow of the resin and the quality of filling; a fine, controlled gradation ensures void-free encapsulation. Quartz filler with low thermal expansion preserves the dimensional stability of the component through temperature changes. Chemical stability and low impurity levels support the insulating performance of the resin. Important note: ultra-high-purity applications such as the fused silica used in semiconductor manufacturing form a separate product class; this page covers epoxy and casting filler applications.

About Electronics
What does quartz filler do in electronics?
In encapsulation and potting resins it improves thermal stability, dimensional balance and electrical insulation properties.
In which electronic applications is quartz filler used?
It is used as a filler material in epoxy-based encapsulation and potting resins.
Is this quartz suitable for semiconductor (chip) manufacturing?
No. Semiconductor manufacturing requires ultra-high-purity fused silica; this product falls within the epoxy and casting filler class.
What fineness is required for electronic filler?
Fine micronised quartz is preferred, as it ensures the resin fills homogeneously and without voids.
