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 silicon micropowders 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 appliance. The majority of copper clad laminates found in smart phones and tablet computers, as well as air conditioners, washing machines, and air conditioners are made from fused silica. The spherical silica powder, which is an epoxy plastic molding compound, has exceptional characteristics, including high fluidity and low stress. Spherical silicon dust fills at a higher rate than angular silica powder. This is a significant advantage over epoxy plastic mold compounds and copper clad laminations. The coefficient of linear extension is most commonly used in high-end copper laminations like aerospace, 5G communications and epoxy plastic packaging materials that are large-scale integrated circuit packaging for smart phones and other wearable devices.

Copper Clad Laminate – Application of silica powder

The addition of performance fillers to copper clad laminating is an important step to improve 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.
