BOROSILICATE

BOROSILICATE GLASS

BJTY is a borosilicate glass type 3.3 as specified in international standard ISO 3585 and BOMEX products meet the most important international standards, for example the German, ASTM. Maximum chemical resistance, minimum thermal expansion and the resulting high resistance to thermal shock are its principal properties. This optimum physical and chemical performance makes BJTY the ideal material for use in the manufacture of chemical plants.
