Due to the much higher density of lead compared to other common metals, lead lined glass also has a relatively high density. This makes it more sturdy and able to withstand greater pressure and impact. In situations where important equipment or sensitive areas need to be protected, lead lined glass can provide better protection. Lead lined glass has excellent chemical stability and can resist the erosion of chemicals such as acid and alkali. This allows it to maintain its protective performance in some special environments, such as in certain chemical laboratories or industrial production lines.

Lead lined glass, with its unique properties, is used in the medical field to make X-ray rooms CT rooms and other radiation protection equipment provide a safe diagnostic and therapeutic environment for medical staff and patients. In the field of scientific research, lead lined glass is used to make various radiation protection devices, such as protective windows and doors in laboratories, to protect researchers from radiation damage.
