Why high borosilicate glass has advantages over tempered glass

Heat-resistant glass withstands rapid cold and heat, which indicates that the thermal expansion coefficient (ratio of glass expansion due to temperature increase) is relatively small and it is not easy to break in rapid temperature changes. It has a series of excellent properties such as low expansion, thermal shock resistance, high temperature resistance, corrosion resistance and high strength. The high borosilicate heat-resistant glass material has a high safety factor, and will never have a self-explosive phenomenon similar to that of tempered glass. It has a small thermal expansion coefficient, a wide range of resistance to rapid temperature changes (≥120 ° C), and a heat resistance of up to 800 ° C. In addition, Borosilicate heat-resistant glass with borosilicate added to the material, also known as Borosilicate glass (LOCK & LOCKGLASS) is a borosilicate glass containing borosilicate.

Tempered glass is also called strengthened glass. The general name for glass products that have been strengthened and have good mechanical properties and thermal shock resistance. Generally referred to as tempered glass refers to flat glass products that have undergone wind hardening treatment. Has high bending strength, mechanical shock resistance and thermal shock resistance. After being broken, the fragments do not have sharp edges and corners, reducing the harm to people. Tempered glass cannot be processed by mechanical cutting or drilling. Mostly used for cars and other transportation vehicles, and doors and windows of buildings. Tempered glass cannot be used in ovens and microwave ovens, and sudden changes in temperature may also cause the glass to explode.
