|Unprocessed PYREX® borosilicate glass comes in unpolished large glass blocks or as rolled glass. It can be sawn, ground, polished and shaped according to customer-specific requirements.|
PYREX® borosilicate glass is a technical glass composition from Corning with excellent thermal properties. A low coefficient of thermal expansion allows a good heat shock resistance and facilitates the use of PYREX® glass at a high operating temperature. Wafers made of PYREX borosilicate glass are an ideal solution for anodic bonding processes, because the thermal coefficient of expansion almost perfectly matches to silicon. A good chemical resistance, much better than the one of soda lime glass, and a high optical transmission over a wide wavelength range, make PYREX borosilicate glass a versatile option for many different special glass applications. PYREX glass can be ground, polished and coated according to custom specific requirements.

Note: The production of PYREX® borosilicate raw glass has been discontinued by Corning many years ago. There is only a small remaining stock existing, so large quantities cannot be offered based on this glass anymore. Nevertheless we have equivalent or superior borosilicate glass materials available that feature an almost identical glass composition and almost identical or better specifications. Please send us your inquiry. We will be pleased to assist you in the selection of the right glass type for your application.
