3.3 high borosilicate glass tube performance and usage introduction

 High borosilicate glass has first -class  level of hydrolysis resistance performance high-borosilicate glass, widely used in laboratory and chemical plants, in recent years in the solar

 heating device on the application have developed rapidly.

Advantages

High borosilicate 3.3 glass product has known as chemical stability, high voltage, resistance to 

thermal shock and excellent processing performance characteristics.

Quality

High borosilicate 3.3 glass production tube, capillary, bar the use of advanced production 

technology production, high borosilicate 3.3 (DIN ISO3585) in the world recognized. The 

production process of every step has strict quality control, and through ISO9001 quality authentication.
