Alkali resistant glass fiber is also called AR- glass fiber. Glass fiber made of alkali resistant glass frit with certain chemical composition. It was first developed in Britain in the late 1960s, and then manufactured in the United States, Japan, China, the former Soviet Union and other countries. Diameter 12-14 μ m. The ultimate tensile strength is 2000-2500Mpa and the elastic modulus is 75-80Gpa. The composition generally contains 14% - 2O% zirconia (ZrO2), so its alkali resistance is better than medium alkali and alkali free glass fiber. It is mainly used to make glass fiber reinforced cement products.

Advantages:
Compared with ordinary alkali free and medium alkali glass fibers, alkali resistant glass fiber has its remarkable characteristics: good alkali resistance, high tensile strength and strong corrosion resistance in cement and other strong alkali media. It is an irreplaceable reinforcing material in glass fiber reinforced cement products (GRC).

Application:
Alkali resistant glass fiber is the base material of glass fiber reinforced cement (GRC). With the deepening of wall reform and economic development, GRC has been widely used in building internal and external wall panels, thermal insulation panels, air duct panels, garden sketches, art sculptures, civil engineering and other purposes. It can make some products and components that are difficult to realize or incomparable to reinforced concrete. It can be used for non load-bearing, secondary load-bearing and semi load-bearing building components, decorative parts, agricultural and animal husbandry facilities, etc.
