A glass
Also known as high alkali glass, it is a typical sodium silicate glass, which is rarely used for the production of glass fiber due to poor water resistance.
E-CR glass
It is an improved boron-free alkali-free glass for the production of glass fiber with good acid and water resistance. Its water resistance is 7-8 times better than that of alkali-free glass fiber. The acid resistance is also superior to that of alkali glass fiber. New varieties developed for underground pipelines, storage tanks, etc.
D glass
Also known as low dielectric glass for the production of low dielectric glass fibers with good dielectric strength.
In addition to the above glass fiber components, a new alkali-free glass fiber is now available, which is completely free of boron, thereby reducing environmental pollution, but its electrical insulation properties and mechanical properties are similar to those of conventional E-glass. There is also a glass fiber with a double glass composition which has been used in the production of glass wool and is said to have potential in the field of FRP reinforcement. In addition, there is fluorine-free glass fiber, which is an improved alkali-free glass fiber developed for environmental protection.
