Glass Rod(Bar) Introduction
3.3 high borosilicate glass performance and usage introduction
Raw material we imported from Europe
High borosilicate glass is one kind of special glass which has first class level of hydrolysis
resistance performance, widely used in laboratory and chemical plants, in recent years
in the solar heating device on the application have developed rapidly.
Advantages
3.3 High borosilicate glass product has known as chemical stability, high voltage, resistance
to thermal shock and excellent processing performance characteristics.
Quality
We adopt advanced platinum molding production technology to produce 3.3 High borosilicate glass tube,
capillary, bar(rod). high borosilicate 3.3 (DIN ISO3585) are recognized in the world. The production
process of every step has strict quality control, and through ISO9001 quality authentication.
Feature:Heat-resistant,acid-resistant,alkali-resistant
