The fiberglass tube can be divided into continuous fiber, fixed-length fiber and glass wool according to its shape and length. According to the glass composition, can be divided into alkali, chemical resistance, high alkali, medium alkali, high strength, high elastic modulus and alkali glass fiber etc.

The main raw materials for producing glass fiber are quartz sand, alumina and pyrophyllite, limestone, dolomite, boric acid, alkali, glauber, fluorite and so on. The production method is divided into two types: one is to make the molten glass directly into the fiber; One is to make the molten glass into a glass ball or rod with a diameter of 20mm, and then heat it in a variety of ways to make a very fine fiber with a diameter of 3 ~ 80 m. It is called continuous glass fiber, which is called continuous glass fiber. A non - continuous fibre made from a roller or airflow, called a fixed-length glass fiber, known as a short fiber. Thin, short, flocculated fibers made from centrifugal force or high speed airflow, called glass wool. Glass fiber is processed, can be made into various types of products, such as yarn, no twist roving, short cut raw silk, cloth, tape, felt, board, pipe, etc.

Glass fiber is divided into different levels according to its composition, nature and purpose. According to the standard (see table), e-glass fiber is the most common and widely used in electrical insulation materials; The s-class is special fiber, although the output is small, but it is very important, because it has super strength, mainly used for military defense, such as bulletproof box, etc. Class C is more chemical resistant than grade E, used in battery separator and chemical filter. Grade A is an alkaline glass fiber used in the production of reinforced materials.

Glass fiber - the main ingredients of its main components in silica, alumina and boron oxide and magnesium oxide, calcium oxide, sodium oxide, etc., according to the amount of alkali content, in the glass can be divided into non-alkali glass fiber (0% ~ 2% sodium oxide, aluminum borosilicate glass), the alkali glass fiber (8% ~ 12% sodium oxide, boron or boron sodium calcium silicate glass) and high alkali glass fiber (more than 13% sodium oxide, sodium calcium silicate glass).
