General properties of calcium soda glass
Soda glass has good chemical and physical properties. Very good chemical resistance to water, saline solutions, acids, bases and organic solvents. It is only attacked by hydrofluoric acid and, at high temperatures, by strong bases and phosphoric acid. Suitable for products that usually only have to withstand short-term chemical stress and do not have to withstand high thermal loads.
