Differences Between the Materials of Tempered Glass Screen Protectors

The demand for smartphones continues to rise, accompanied by larger and curved screens. One significant driver of this demand is the escalating cost of replacing damaged original screens, prompting consumers to opt for tempered glass screen protectors. These protectors provide an effective and cost-effective solution to safeguard mobile phone screens.

Tempered glass screen protectors are predominantly made from glass and are available in various types from different manufacturers. This article explores and analyzes the differences between these materials and their importance.

Glass Types

a) Calcium Sodium Glass

Calcium sodium glass, commonly found in everyday products like windows and glass doors, is characterized by its durability and affordability. It typically has a green tint due to its high calcium and sodium content and ranges in thickness from 0.2mm to 0.4mm. The light transmission rate of calcium sodium glass falls between 92% and 94%.

Advantage: Affordability and decent light transmission rate.

b) High-Aluminum Silicon Glass

High-aluminum silicon glass, often referred to as white glass, is favored for its low impurity content, resulting in a white tint. Renowned manufacturers such as Corning and Schott utilize this glass due to its superior ductility. It ranges in thickness from 0.1mm to 0.33mm and boasts a light transmission rate between 94% and 96%.

Advantage: Superior ductility, ability to bend and fold post-tempering, and higher light transmission rate.

Market Considerations

Manufacturers cater to varying market demands by producing tempered glass screen protectors using both types of glass. Consumers must consider their needs and budget when selecting a screen protector for their smartphones.

Manufacturer Insights

Not all manufacturers produce both types of tempered glass screen protectors. For instance, Corning Glass focuses on thicker glass for mobile phone covers, which are more expensive and less suitable for screen protectors thinner than 0.8mm.

Conclusion

Choosing the right material for a tempered glass screen protector is crucial to its quality and effectiveness. While calcium sodium glass offers affordability and adequate light transmission, high-aluminum silicon glass provides superior flexibility and higher light transmission. Understanding these differences empowers consumers to make informed choices based on their preferences and budget.
