What Is Heat-Resistant Glass And Technical Glass?

Technical Glass refers to glass with special or comprehensive properties used in certain technical departments. Mainly include optical glass, chemical glass, safety glass, electronic glass, protective glass, etc. Heat-resistant glass is a kind of Technical Glass.

Heat-resistant glass is a kind of glass with strong ability to withstand the thermal shock caused by sudden cold or sudden heat (small thermal expansion coefficient, thermal expansion coefficient (3.2~4.5)×10^-6/℃), high working temperature (high strain temperature and softening temperature). The heat-resistant glass has some excellent properties such as low expansion, thermal shock resistance, high temperature resistance, corrosion resistance, and high strength. The main property of heat-resistant glass is thermal shock resistance. The unique physical and chemical properties determine that the glass is a amazing material with wide range of applications material.

Borosilicate glass, Aluminosilicate glass, and Quartz glass can be called heat-resistant glass by the high working temperature, but people are more accustomed to call borosilicate glass heat-resistant glass. Internationally well-known brands of borosilicate glass include USA’s Pyrex glass, Germany’s "Duran-50", Britain’s "Hysil", and Japan’s "Terex". Now Chinese borosilicate glass become more and more popular in the market because of similar characteristics of low thermal expansion coefficient, high thermal stability, high mechanical strength, strong acid resistance (except HF acid), high softening point, and excellet thermal shock resistance. And most of all cost-effective product is our main advantage.

Specific uses of Heat-Resistant Glass are as follows:   

1. Use of high-temperature industrial equipment   

This kind of glass can be used as a sight glass for high-temperature containers, piping equipment, boiler special equipment and other machinery. Such as Sight Glass Disc, borosilicate tubular gauge glass, reflexion gauge glass and transparent gauge glass.

2. Heating equipment using   

heat-resistant glass can be used for heating equipment, such as fireplaces, wave soldering equipment, ovens, fire holes, etc.  

3. Use in thermal power plants and metallurgical fields   

The Heat-Resistant Glass can be used in thermal power plants, steel plants, electrolytic aluminum plants, and can withstand extremely high temperatures.   

4. Use of optical equipment   

The Heat-Resistant Glass can be used for optical equipment that needs high temperature resistance and requires ultraviolet light, infrared light, infrared light, and laser protection.  

5. Heat-resistant lamps

The Heat-Resistant Glass can be used for buried lamps and all kinds of high-temperature lamps.
