Borosilicate glass was originally named "Borosilicate glass 3.3" internationally because its linear thermal expansion coefficient (3.3×10-6K-1) conforms to the ISO 3585 "Borosilicate glass 3.3" standard.
On the basis of borosilicate 3.3 flat glass, borosilicate float glass with a linear thermal expansion coefficient of 4.0×10-6K-1 is further produced, which is called "borosilicate 4.0 flat glass" according to this custom.
According to the fire resistance time:
The fire resistance time limit is 0.5h, it is recommended to use cesium potassium fireproof glass and high-stress fireproof glass.
The fire resistance time limit is 1.0h, it is recommended to use high-stress fireproof glass.
The fire resistance time limit is 1.0h and more than 2.0h, and the size is larger than 3 meters. It is recommended to use high borosilicate fireproof glass.
