China high borosilicate glass tubes with difference size

Made of borosilicate glass material
High temperature resistant
Adopt platinum molding technology
Length: as customer's demand

 

 

We have our own furance for the production of those glass tubes, we can customize the specifications to the customers' demand, and the delivery time will be very short.

Our glass tubes can keep high brightness for longer time than other glass, and looks more transparent due to the borosilicate material.The outer diameter is 8~315mm, wall thickness is 1.0~10mm, and the length is freeAdopt platinum molding technology to produce 3.3 high borosilicate glass,
Looking forward to establish business relationship with you!
