Type I glass, also known as borosilicate glass, is renowned for its superior chemical resistance and thermal stability. It is composed of boron trioxide and silica, which make it highly durable and suitable for a wide range of applications. Type I glass is commonly used in the pharmaceutical industry for packaging injectable drugs, laboratory glassware, and other sensitive products that require the highest level of protection against chemical reactions and thermal shock. This glass type ensures the integrity and safety of its contents, making it the preferred choice for critical and high-purity applications.
