Glass tube introduction
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~315mm Glass rods dia from 4~42mm Glass wall thickness: 1.0mm~10mm Technical data for glass tube Main composition:
