Also known as alkali free glass, is a kind of borosilicate glass. At present, it is the component of a glass fiber used most widely used glass, with good mechanical strength and electrical insulation, widely used for electrical insulation glass fiber production, can also be used for glass fiber production of glass steel. However, the shortcoming is it is easy to be inorganic acid erosion, therefore not suitable for usein acidic environment.


Alkali glass also known as, its characteristic is the chemical resistance, ,especially the resistance to acid is better than that of alkali free glass, but poor electrical performance, mechanical strength is lower than the non alkali glass fiber is 10% ~ 20%, three boron oxide containing certain quantity of medium alkali glass fiber usually abroad two, while alkali glass fiber China is completely free of boron.
