Our company imports and sells glass products. Let me briefly introduce the "properties of glass." Like metals, glass expands and contracts with temperature changes. It is classified as 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.

Our company imports and sells glass products. We would like to introduce the raw materials and their properties related to glass. "Silica sand" is used to obtain SiO2, which forms the framework of glass. Depending on the type of glass, 60% to 80% of the raw materials are silica sand. Impurities contained in silica sand can sometimes cause discoloration. "Calcium" is used together with sodium in soda-lime glass. Limestone is commonly used, which improves moldability and water resistance. In addition to this, "magnesium" and "zinc oxide" are also used as raw materials for glass. If you are looking for glass products, please feel free to contact us. [Main Raw Materials (Partial)] ■ Silica sand ■ Sodium ■ Calcium ■ Boron oxide ■ Alumina *For more details, please refer to the PDF document or feel free to contact us.

Our company imports and sells glass products. We will introduce glass that is not commonly seen and glass used in very 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.

Our company imports and sells glass products. There are many types of glass available depending on their intended use. Here, we will introduce some very basic points for selecting materials. First, soda glass is cost-effective. If you do not need to worry about the environment or temperature, choose soda glass, which is easy to make 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, it is better to choose 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, then opt for aluminosilicate glass.
