Points for Choosing Materials

Introduction to key points for selecting materials: soda glass, borosilicate glass, and aluminosilicate glass.

Our company imports and sells glass products. There are many types of glass available depending on the application. Here, we will introduce some very basic points for selecting materials. First, soda glass is cost-effective. If you do not need to pay attention to the environment or temperature, choose soda glass, which is easy to produce and low in cost. For example, if you are in an environment where there are sudden temperature changes above 80 degrees or in a consistently humid environment, opt for borosilicate glass, even if it is somewhat more expensive. If you need to use glass in an environment exceeding 500 degrees, which borosilicate glass cannot withstand, choose aluminosilicate glass. If you are looking for glass products, please feel free to contact us. *For more details, please refer to the PDF document or feel free to reach out to us.

Properties of glass

I will introduce the properties of glass, such as thermal expansion!

Our company imports and sells glass products. Here is a brief introduction to the properties of glass. Like metals, glass expands and contracts with temperature changes. It is classified as either heat-resistant glass or regular glass based on differences in thermal expansion coefficients. Compared to regular glass, the thermal expansion coefficient of heat-resistant glass is about 1/2 to 1/3. Because it has a lower expansion coefficient, it can withstand sudden temperature changes. It is necessary to choose glass that is suitable for the usage environment based on the thermal expansion coefficient. If you are looking for glass products, please feel free to contact us. [Properties] ■ Strength of glass ■ Thermal expansion of glass ■ Color of glass ■ Durability of glass *For more details, please refer to the PDF document or feel free to contact us.

Special glass

We will introduce special glasses such as quartz glass and high-refractive glass!

Our company imports and sells glass products. We introduce glass that is not commonly seen and glass used in extremely harsh environments. "Borosilicate glass" is sometimes referred to as hard glass or heat-resistant glass. It has a low coefficient of thermal expansion, making it resistant to breaking even when hot water is poured into it. "Aluminosilicate glass" is primarily made from alumina (Al2O3) and silica (SiO2), and has a glass transition temperature of around 650 to 700 degrees, allowing it to be used in higher temperature environments. If you are looking for glass products, please feel free to contact us. 【Features】 ■ Borosilicate glass - Low coefficient of thermal expansion, resistant to breaking even when hot water is poured in - Low alkali leaching and excellent water resistance ■ Aluminosilicate glass - Primarily made from alumina (Al2O3) and silica (SiO2) - Used in high-temperature environments *For more details, please refer to the PDF document or feel free to contact us.
