Clear 3.3 high borosilicate glass tubing wall thickness 1-6mm

Product Description

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.

1. Our glass tubes can keep high brightness for longer time than other glass, and looks more transparent due to the borosilicate material.
2. The outer diameter is 8~**5mm, wall thickness is 1.0~*0mm, and the length is free
3. Adopt platinum molding technology to produce borosilicate glass,Looking forward to establish business relationship with you!

The material is high borosilicate 3.3. Which imported from European,super quality raw material assure us

 supply quality goods.

Borosilicate 3.3 series glass is a kind of special type glass material with the features of low expansion coefficient,high temperature resistance,high intensity, high rigidity, transparency and chemical stability. It doesn't explode in high temperature, and can be forged and drawn to variety of formation when soften.

All these splendid features enable it to be widely used in the field of solar energy,chemical industry, pharmaceutical packaging, electric light source,artificial crystal, artificial craft decoration and so on.Compared with ordinary glass. It's non poisonous, and it has made the big progress in its mechanical property, thermal stability, hydrolytic resistance.acid resistance and alkali resistance glass

High borosilicate glass products:
We can provide a full range of borosilicate glass products, such as borosilicate tube, glass rods
Glass tube OD from 8mm~**0mm
Glass rods dia from 6~*2mm
Glass wall thickness: 1.0mm~6.0mm
