PYREX® GLASS PRODUCTS IN MONTREAL

Pyrex® sheet is low-expansion borosilicate glass manufactured by Corning. MP Glass in Montreal can cut and size Pyrex® sheet to customers' specifications. We can also temper Pyrex® to increase its mechanical strength and heat resistance. BorofloatTM is also a highly chemically resistant borosilicate glass with a low thermal expansion, but because it is manufactured by the float method, it possesses the additional characteristic of unsurpassed smoothness.
