Product Description
Product Application
Linear expansion coefficient G3.3 borosilicate glass is 3.3 persons 0.1 × 10-6 / K, based on sodium oxide (Na2O), boron oxide (B2O3), silicon dioxide (SIO2) as a basic ingredient of glass. The borosilicate glass composition higher content of boron, respectively: 12.5 to 13.5%, Si: 78 to 80%, so that this type of glass is borosilicate glass. Belonging borosilicate glass PYREX glass. Acid and alkali water, excellent corrosion resistance, has good thermal stability, chemical stability and electrical properties, it has a chemical resistance, thermal shock resistance, good mechanical properties, withstand high temperature and other characteristics.
