High Borosilicate Glass

High borosilicate glass is a type of glass that is made by adding boron oxide to silica glass. It is known for its excellent thermal shock resistance, high chemical durability, and low thermal expansion coefficient, which makes it a popular choice for a wide range of applications.

Borosilicate glass is made by melting a mixture of silica and boron oxide at high temperatures. The addition of boron oxide to the glass composition reduces the thermal expansion coefficient of the glass, making it more resistant to thermal shock. Borosilicate glass also has a high chemical resistance, making it ideal for use in laboratory glassware and chemical processing applications.

 

High borosilicate glass has several advantages over other types of glass. For example, it can withstand rapid temperature changes without cracking or breaking, making it ideal for use in cooking and baking applications, such as glass baking dishes, as well as in scientific and laboratory applications, such as test tubes and beakers. Additionally, it has a high level of clarity and transparency, making it an excellent choice for use in optics, such as lenses and prisms.

Other applications for high borosilicate glass include solar energy systems, pharmaceutical packaging, and electronic display screens. Its unique properties, including its high strength, chemical resistance, and thermal stability, make it a versatile and valuable material for many different industries.

Overall, high borosilicate glass is a valuable material with a wide range of applications. Its unique properties make it an excellent choice for use in a variety of high-performance applications where strength, durability, and resistance to thermal shock and chemical corrosion are critical.

FAQ

Q: Should glass be tempered and what's the difference between Chemical tempered and Physical tempered? 

To small size/thickness less than 3.2mm,we recommend chemical tempered.(surface toughen by 6-7H).

To bigger size/thickness above 3.2mm, we recommend physical tempered.

Base on thermal tempered, the fragmentation test standard / partical sizes & quantity could be set base on different thickness.

The glass flatness could be asked after tempering.

 

Q: What kind of glass will be used? 

LightingWe usually use clear / ultra clear float glass for production, depends on customer's need.

Cover glassWe usually use AGC(Dragontail) for production, but also available in gorilla/NEG etc. base on customer's need

Furniture glass We usually use high quality flat/bending glass
