Product Details

Product Description

The fused silica powder is made of natural high-quality quartz, which is melted by high temperature and theamorphous silicon dioxideafter cooling is used as the main material, and then processed by unique technology. The product has high purity, low thermal expansion coefficient, low internal stress, high moisture resistance and low radioactivity. As a plastic sealing material for enclosed integrated circuits, it has the outstanding advantages of good dynamic performance, less spills/spillage and large filling capacity.

Application

Fused silica powder is widely used in electronic packaging, investment casting, high-grade electrical insulation, paint and coatings, silicone rubber, refractories, high-grade plastics, special ceramics and other industries.

Main Features:

1. Extremely low linear expansion coefficient and low internal stress.

2. High purity, good whiteness and uniform particle size distribution.

3. Good electromagnetic radiation.

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

5. Stable chemical properties and high moisture resistance.

6. Good acid and alkali resistance, high temperature resistance and insulation performance.
