Alkali-Free Fiberglass


Alkali-free glass fiber R2o content is less than 0.8%, is an aluminum boron silicate composition. Its chemical stability, electrical insulation performance, strength are very good. Mainly used as electrical insulating material, FRP reinforced material and tire curtain line. Used for composite cable brackets. The content of alkali glass fiber R2o is 11.9%-12.4%, which is a kind of sodium-calcium silicate component, because of its high alkali content, it can not be used as electrical insulating material, but its chemical stability and strength are good. Generally used as latex cloth, gingham base material, acid filter cloth, window screen substrate, etc., but also against the electrical properties and strength of the requirements of the FRP reinforced material is not very strict. The defects of high alkali glass fiber, such as low strength, poor water resistance and alkali resistance, can not be overcome. Using it as an enhanced product will ultimately only harm the interests of the user. Glass fiber is a kind of inorganic nonmetal material with excellent performance. English formerly known as: Glass fiber or Fiberglass. The composition is silica, alumina, calcium oxide, boron oxide, magnesium oxide, sodium oxide, etc. It is a glass ball or waste glass as raw materials by high-temperature melting, drawing, winding, weaving and other processes.
