Silicon powder has two resistance, three high, three low excellent properties, so it is widely used in copper clad plate industry.
With the improvement of the surface treatment conditions of silicon powder, it has improved its compatibility with the resin system, so the application of silicon powder as a filler in the copper clad plate can not only reduce the cost, but also improve some properties of the copper clad plate (such as thermal expansion coefficient, bending strength, dimensional stability, etc.), which is a real functional filler.
