CORNING PYREX SG3.3 Borosilicate Glass
CORNING PYREX SG3.3 is a high borosilicate glass with extremely high chemical stability and excellent thermal expansion properties, especially suitable for use in high temperature and strong corrosive environments. SG3.3 glass gets its name from its excellent low coefficient of thermal expansion (approximately 3.3×10⁻⁶/K), which enables it to maintain a stable form under conditions of large temperature changes and avoid damage caused by thermal stress. In addition to its powerful physical properties, PYREX SG3.3 is highly transparent and is an important part of laboratory equipment, chemical containers and various precision instruments.
