大阪硝子工業 List of Products and Services

Pyrex is borosilicate glass made by Corning Inc. in the United States. It has excellent corrosion resistance, extremely low alkali content, a small linear expansion coefficient, and outstanding thermal shock resistance. Tempax is borosilicate glass made by Schott AG in Germany. It has a small average thermal expansion coefficient and demonstrates excellent heat resistance and thermal shock resistance in various fields. The microfloat process results in a flat and smooth surface finish, combining high light transmittance with excellent optical quality and minimal optical distortion. 【Features】 ■ Pyrex ○ Borosilicate glass made by Corning Inc. in the United States ○ Excellent corrosion resistance with extremely low alkali content ○ Small linear expansion coefficient of 32.5X10⁻⁷/cm/cm/℃ (0-300℃) ○ Outstanding thermal shock resistance ■ Tempax ○ Borosilicate glass made by Schott AG in Germany ○ Small average thermal expansion coefficient of 32.5×10⁻⁷/cm/cm/℃ (0-300℃) ○ Demonstrates excellent heat resistance and thermal shock resistance in various fields ○ Excellent optical quality with high light transmittance and minimal optical distortion *For more details, please refer to the PDF document or feel free to contact us.
