Heat-resistant glass can be used for microwave oven heating, high-temperature oven, hot water disinfection equipment, as well as household appliances such as refrigerator refrigeration and dishwasher.

Due to the different materials, heat-resistant glass can withstand the highest temperature 1500 degrees (the highest softening point 1730 degrees), which is chemically stable, corrosion-resistant and will not precipitate harmful substances.

Characteristics of heat-resistant glass

Heat-resistant glass (special glass containing boric acid and silicic acid, which has strong heat resistance and can withstand the temperature difference change of hot and cold fusion). The coefficient of thermal expansion (the ratio of glass body expansion caused by temperature rise) is relatively small, and it is not easy to break under the condition of rapid temperature change. It has a series of excellent properties such as low expansion, thermal shock resistance, high temperature resistance, corrosion resistance and high strength.

The raw material price of heat-resistant glass is higher than that of ordinary glass, and the manufacturing cost is also higher, so the sales price of heat-resistant glass is higher than that of ordinary glass and tempered glass. Heat-resistant glass has a high safety factor and will never explode like tempered glass. Heat-resistant glass is mostly used in utensils, milk bottles, experimental beakers, industrial boiler mirrors, mechanical equipment windows and so on.
