Tempered glass is a type of glass that undergoes a strengthening process, making it significantly stronger than ordinary glass. It employs a heat treatment process where the glass is first heated to a high temperature and then rapidly cooled, creating compressive stress on the surface. This process substantially enhances its hardness and impact resistance.
Core Advantages
The most prominent feature of tempered glass lies in its safety upon breakage. Unlike ordinary glass that shatters into sharp shards, it fractures into small, blunt-edged particles, greatly reducing the risk of personal injury.
Primary Applications
Thanks to its superior strength and safety, tempered glass is widely used in architectural doors and windows, furniture (such as glass tables), automotive side and rear windows, and various touchscreen devices.
Tempered glass is further categorized into physically tempered and chemically tempered varieties. When selecting glass types, understanding the differences between these two processes is essential. As a professional in high-quality touch display and computer manufacturing, I recognize that choosing the correct glass type is critical to product performance. Below is a concise overview of their characteristics and suitable applications.
Physically Tempered Glass: Produced by rapidly cooling glass after high-temperature heating, creating a high-strength compressive layer on the surface. This enhances its impact and bending resistance to five times that of ordinary glass.
Key characteristics include:
High mechanical strength, suitable for scenarios with high safety requirements;
Breaks into small fragments without sharp edges, ensuring good safety;
Scratch-resistant, ideal for industrial touchscreens and public facilities.
Applications: Industrial touchscreens, laboratory windows, safety partitions, etc.
Chemically Tempered Glass: Employing an ion exchange process, the glass is immersed in molten potassium salt, replacing surface sodium ions with potassium ions. This enhances overall strength while maintaining high optical performance.
Key characteristics include:
Uniform strength distribution, minimizing deformation;
High light transmittance for superior visual experience;
Enhanced edge strength, suitable for ultra-thin designs.
Applications: Camera lenses, microscope slides, ultra-thin electronic device covers, etc.
Daily maintenance of tempered glass is straightforward. Use a soft cloth with a neutral cleaner, avoiding hard or abrasive tools to prevent surface scratches.
In industrial displays and computer equipment, selecting the appropriate tempered glass is critical to product performance. Physically tempered glass excels in strength and impact resistance, while chemically tempered glass offers superior optical properties and thin-profile design advantages. Understanding these distinctions enables optimal selection based on specific requirements, enhancing product reliability and user experience.
