Borosilicate Glass Sheet

Borosilicate Glass Sheets are amorphous and transparent silicate glass with low thermal expansion and high chemical resistance. Their high temperature stability and high shock resistance, make them suitable for applications such as laboratory glassware, pharmaceutical packaging and heat-resistant windows. Goodfellow offers Borosilicate Glass Sheets in a variety of thicknesses, with polished or unpolished surfaces, to meet diverse application requirements across science and industry.
