What is silica?

Silica powder can be made from natural quartz, fused silica and others. as raw materials. They are then processed through multiple processes, such as grinding and precision classification. The most popular products are fused silica powder and crystalline silicone powder. Micropowders and spherical micropowders of silica are two examples.

Silica powder has a wide range of applications.

Crystalline silica is used primarily for copper clad laminations in refrigerators, air conditioners, and other household appliances. The majority of copper clad laminates found in smart phones and tablet computers, as well as air conditioners and washing machine, are made from fused silica. The spherical silica powder, which is one of many epoxy plastic molding materials, has exceptional characteristics, including high fluidity and low stress. The filling rate for spherical silica powder is much higher than that for angular silica powder. This allows you to reduce the copper clad laminates as well as epoxy plastic molding compound. The coefficient of linear extension is used most often in high-end copper laminates like aerospace, 5G communications and epoxy plastic packaging materials that are large-scale integrated device packaging such as smart phone and wearable devices.

Copper Clad Laminate – Application of silica powder

It is important to add performance fillers to copper clad laminate’s production formula to increase heat resistance and reliability. Silica powder is widely used as a filler in the copper-clad laminate industry because it has many advantages, including heat resistance, dielectric property, linear expansion coefficient, and dispersibility within resin systems.

Epoxy Molding Compound – Application of silica powder

A molding compound that is composed of epoxy resin as matrix resin and high-performancephenolic resin curing agent. Silicon powder can be used as filler. The epoxy molding compound composition consists of 60-90% filling rate.
