- May 15, 2019-

Its main components are silica, alumina, calcium oxide, boron oxide, magnesium oxide, sodium oxide, etc. According to the alkali content of the glass, it can be divided into alkali-free glass fiber (sodium oxide 0%~2%, belonging to aluminum) Borosilicate glass), medium alkali glass fiber (sodium oxide 8%~12%, is a soda-calcium silicate glass containing boron or boron) and high alkali glass fiber (sodium oxide is more than 13%, which is sodium calcium) Silicate glass).
