Description

Toughened glass, also known as tempered glass, is a type of safety glass that has been heat-treated to increase its strength. The process involves heating the glass to a high temperature (around 620°C or 1148°F) and then rapidly cooling it through a process called quenching. This creates compressive stresses on the surface of the glass, making it much stronger than regular glass and more resistant to impact and thermal shock.

Key Characteristics:

1. Strength: Toughened glass is significantly stronger than standard annealed glass—about four to five times stronger.
2. Safety: When broken, toughened glass shatters into small, blunt pieces rather than sharp shards, reducing the risk of injury.
3. Thermal Resistance: It can withstand higher temperature variations compared to regular glass, making it ideal for environments subject to rapid temperature changes.
4. Durability: The increased strength of toughened glass makes it more resistant to scratches, cracks, and other forms of wear and tear.

Common Uses:

• Windows and doors in buildings and vehicles, where safety and strength are paramount.
• Shower enclosures and glass partitions, which need to handle both physical impact and exposure to water and heat.
• Smartphone screens and other electronic displays, where durability and scratch resistance are key.
• Oven doors and cooktops, which are exposed to high temperatures.

Toughened glass is often used in situations where safety is a concern, as well as where glass must endure high-impact stress or temperature extremes.
