Excellent visual effect2. Powerful effect on Fire, hydrolysis and Chemical Resistance3. High resistance to thermal shock.BOROSILICATE FLOAT GLASS DEscriptIonBolipai GLASS 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. It is also used in the processing of high-level nuclear waste, where the waste is immobilised in the glass through a process known as vitrification (contrast with Synroc).BOROSILICATE FLOAT GLASS 3.31.
