What is ultra-clear glass? Why choose low iron glass?

Introduction: What is ultra-clear glass?

Ultra-clear glass is also known as low iron glass. By reducing the iron content in the glass, the glass has a crystal texture visual. There is no greenish visual effect like ordinary clear glass, whether viewed from the front or the side. With high light transmission to 91.5%, it has superior mechanical, physical, and optical properties.

Moreover, it can do all secondary processes like clear float glass: Tempering, laminating, insulating, coating, curving, etc. Then, make ultra-clear toughened glass, ultra-clear laminated glass, ultra-clear curved glass, etc., for different glass products.

Benefits: Why choose low iron glass?

Low self-explosion rate

Firstly, its raw materials contain fewer impurities. In addition, the control is fine during the melting process of raw materials, making it a more uniform composition than clear float glass. As a result, it has a much lower self-explosion rate after tempering.

Color consistency

The iron content in the raw material is only 1/10 or even lower than that of clear glass. So low iron glass absorbs fewer green and purple bands in visible light than regular glass, ensuring the consistency of glass color.

High light transmission

Low iron glass has many industrial applications because of its unique high light transmittance of 91%. For example, using it as the substrate of the solar photoelectric system can dramatically improve the conversion efficiency.

Applications: Where to use ultra-clear glass?

Glass furniture, museum showcases, jewelry displays, high-end shopping malls, shopping mall spaces, brand stores, aquarium, etc.

Electronic products, automotive glass, solar cells, solar photovoltaic power generation systems, lighting fixtures, scanners, etc.

Building curtain walls, such as high-end hotels, city landmarks, government building projects, exhibition venues, etc.
