1. Borosilicate glass

The main type of glass that produces by PROMSYSTEMS

  Borosilicate glass - contains boric oxide as well as several other ingredients in specific proportions. The inclusion of boric oxide results in a glass material with excellent thermal properties. The material has a different coefficient of thermal expansion and very high resistance to thermal shock depending on the type of glass and customer requirements. As a result, it retains its dimensions across different temperatures and resists cracking and shattering when exposed to rapid temperature changes.

2. Advantages of glass

Let's consider its advantages over Soda-Lime type glass as an example:

  1. ​Borosilicate glass is harder, which allows it to be fabricated into more intricate and complex shapes.

  2. Borosilicate glass is more resistant to chemicals.

  3. Borosilicate glass is more thermally stable, which allows it to withstand use in applications where it is subjected to high or low temperatures.

3. Applications of Borosilicate Glass

  • Thermal insulation: Borosilicate glass can be used to withstand high temperatures when compared to soda lime in severe applications.
     

  • Scientific lenses and hot mirrors: Due to its low coefficient of thermal expansion, borosilicate glass maintains the same optical properties across a range of temperatures, making it an ideal material for scientific lenses and other high-precision optical components. This type of glass is also used in the fabrication of hot mirrors, which are designed to protect sensitive optical systems by reflecting infrared light.

  • High-intensity lighting: Glass receptacles and membranes used in high-intensity lighting systems are often made from borosilicate glass, which allows them to tolerate the intense heat generated during continuous operation. Examples of lighting products with borosilicate glass components include high-intensity discharge (HID) lamps and studio or stage lighting.
     

  • Ceramic bond: Borosilicate glass is commonly used as an additive for the manufacture of high-strength workpieces that include mixing components with ceramics, abrasives, or other chemical compounds.
