This is a glass plate with a low thermal expansion rate and excellent heat resistance. It is equivalent to Pyrex. We will manufacture it in the size you desire.
Tempax is a borosilicate glass from the German company Schott, which has a low thermal expansion coefficient and exhibits excellent heat resistance and thermal shock resistance in various fields. For items with a thickness of 20t or less, we prepare standard products with a flat surface finished by the float process. There are also several types of roll plates with thicknesses ranging from 28.6 to 57.2t, so while polishing is necessary, we can also supply thicker plates over 20t.
