Feature
+
With a small thermal expansion coefficient, borosilicate striped glass tube offers excellent thermal stability, chemical stability, and electrical properties. It also exhibits outstanding resistance to chemical erosion, thermal shock, and mechanical stress.
- Thermal Resistance: Borosilicate glass tubes can withstand extreme temperatures without cracking or shattering, ensuring reliable performance in lighting applications.
- Durability: These tubes possess excellent mechanical strength, making them highly durable and resistant to breakage, ensuring long-lasting reliability in demanding lighting environments.
- Chemical Stability: Borosilicate glass tubes are remarkably chemically stable, resisting corrosion from acids, alkalis, and other chemicals commonly encountered in lighting applications, thus ensuring an extended service life.
Application
+
Borosilicate glass is applied in various areas.
- Laboratory Glassware: Its resistance to chemical reactions makes borosilicate glass perfect for laboratory settings, where it is used to make beakers, test tubes, and other scientific instruments that require exposure to different chemicals.
- Lighting: Borosilicate glass tubes are used in lighting due to their ability to withstand high temperatures without compromising structural integrity. This is crucial for lamps and other lighting devices that generate significant heat.
- Cookware: The glass’s ability to handle rapid temperature changes makes it suitable for kitchenware like baking dishes and stove-top cookware, allowing it to go from freezer to oven without breaking.
- Optical devices: The glass is also used in the production of optical devices like lenses and mirrors due to its high transparency and low thermal expansion, which are critical for precision applications.
