Sell China factory produced high purity white electronic grade silica powder

Product Description:

Electronic silica powder is a kind of inorganic non-metallic mineral functional powder material, which is made of natural high-quality low conductivity quartz ore and fused quartz by fine processing such as color separation, purification, magnetic separation, grinding and precision classification. Electronic silica powder is designed for the packaging requirements of electronic components. It has the characteristics of high silica content, low ion content and low conductivity.

Application:

It is widely used in insulating pouring of electronic components. The sintering temperature of electronic substrates (electronic ceramics) can be reduced by adding ultra-fine and ultra-pure quartz powder, and it can toughen, compact and enhance the strength of two-phase and multi-phase. It is the basic material for packaging adhesive products in the electronics industry. The electronic packaging materials used for LED, SMD, EMC electronic separation devices and electrical products are mainly waterproof, dust proof, harmful gas proof,vibration mitigation, external force damage prevention and circuit stability.

Main features:

1. High purity, good whiteness and even particle size distribution.

2, Low ion content, low conductivity, excellent electrical insulation.

3. Stable chemical properties, no reaction with any other substances except hydrofluoric acid and strong base.

4. Low oil absorption, low viscosity, good dispersibility and fluidity.

5, Small shrinkage, small thermal expansion coefficient, acid and alkali resistance, high temperature resistance, good insulation performance.

6. Good mechanical performance and good transparency when mixed with epoxy resin.
