This chemically resistant type of borosilicate glass contains a high percentage of silica and a considerable amount of boric oxide. It can be ground, drilled, polished and toughened

Its low thermal expansion, high thermal shock resistance and its ability to withstand temperatures up to 450°C for long periods make this material a good choice for applications which call for good temperature stability

It is very resistant to attack from water, alkalis, acids and organic substances

With good chemical durability and a thermal expansion allowing a high level of pre-stressing (toughening) which gives excellent resistance to thermal shock

These materials are specially selected, for the manufacture of flat gauge glasses intended for Steam and Hydrostatic applications
