South Source Core imports high quality thermal insulator glass from the US and Japan. Its good sintering property has made sure our products' air tightness, electrical property and mechanical property always at best performance.

Besides, the glass has good thermal expansion coefficient and constant heat insulation. Its softening point, annealing point, working point, density and so on play a key role in assuring the products' overall air tightness, electrical property and mechanical property.

The metal materials used in glass sintering are selected with care. We did so to ensure its thermal expansion coefficient matched with its materials. As such, the metal properties of the products such as high tensile strength, hard, malleable, impact toughness, fatigue strength, fracture toughness remain in good condition even after sintering process.
