Soda glass is heated to a certain temperature (which varies depending on the raw materials) and then rapidly cooled by blowing compressed air onto it, creating a compressive layer on the glass surface. This results in a glass that is approximately 2 to 3 times stronger than in its normal state (air-cooled strengthening). In this case, strength refers to bending strength, which is improved regarding the pressure applied to the pressure vessel when installed. The main raw materials used for strengthening treatment are soda glass and low-expansion borosilicate glass (such as Pyrex and Tempax). Please select according to your intended use (pressure-resistant specifications or heat-resistant specifications). 【Features of Soda Glass】 ■ Maximum operating temperature: 80℃ ■ Minimum bending strength: 150N/mm² ■ Average linear expansion coefficient: 98×10^-7/℃ or less *For more details, please refer to the PDF document or feel free to contact us.
