Borosilicate glass tube

High heat resistance borosilicate tempered glass tube. borosilicate glass has higher chemical resistance than ordinary glass, high resistance to heat and temperature changes. Its composition can be found between 70% and 80% sand, 7% to 13% boron trioxide, between 4% and 8% sodium oxide and potassium oxide and finally between 2 % and 7% aluminum oxide. Thanks to its properties, borosilicate glass is widely used in production plants in the chemical sector, in the pharmaceutical industry, in materials.
