Borosilicate glass tubes

The material is borosilicate the working temperature is 500-700C.

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,transparence and chemical
dosen'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.
