Some of the benefits of this type of material are:

•   It is highly resistant to thermal shock.

•   It is very durable, which makes this products easy to handle at daily use

•   Its low expansion coefficient permits its use under extreme temperature conditions.

•   Boroclass blender jar can be taken hot from the dishwasher and used immediately to prepare a frozen drink.

•   With proper use, It can last for many years maintaining the same appearance, transparency and resistance.

•   Does not scratch or stain and does not retain odors.

•   It is a highly secure material which is also used for laboratory products.

Chemical composition
Borosilicate Glass has the following approximate composition (%):
SiO2= 81%  B2O3= 13% Na2O + K2O= 4%  AI2O3= 2%
