Product Description
Wholesale customized high quality and low price various colors of borosilicate glass tube
Borosilicate glass tube 3.3
Borosilicate glass has a very low thermal expansion coefficient, about one-third that of ordinary glass. This reduces material
stresses caused by temperature gradients, thus making it more resistant to breaking. This makes it a popular material for objects
like telescope mirrors, where it is essential to have very little deviation in shape.
Borosilicate COE3.3 glass tubing:
1. Diameter available: 3.5mm~300mm
2. Wall thickness: 0.8mm~12mm
3. Length: 1220mm~3000mm
4. Regular sizes: 9*2, 12*2, 25*4, 28*4, 32*3.2, 32*4, 38*4, 44*4, 51*4, 50*5.
5. The high borosilicate 3.3 glass tube is used forlab equipment, optical, medical, daily glassware, solar energy, test tube, etc.
6. We can supply special dimensions according to request.
Chemical Composition
SiO2: 81%
B2O3: 13%
Na2O+K2O: 4%
Al2O3: 2%
