Glass Fiber is a kind of inorganic non-metallic material with excellent performance and a wide range of types, the advantages are good insulation, heat resistance, good corrosion resistance, high mechanical strength, but the disadvantage is brittle, poor wear resistance. It is made of glass balls or waste glass as raw material by high temperature melting, drawing, yarn, weaving and other processes, its monofilament diameter of a few microns to more than twenty microns, equivalent to a hair of 1/20-1/5, each bundle of fiber filaments are composed of hundreds or even thousands of monofilaments. Glass fiber is commonly used as reinforcing material in composite materials, electrical insulation materials and thermal insulation materials, circuit substrates and other areas of national economy.

The main components of Glass Fiber:

Its main components are silicon dioxide, aluminum oxide, calcium oxide, boron oxide, magnesium oxide, sodium oxide, etc., according to the amount of alkali content in the glass, can be divided into alkali-free glass fiber (sodium oxide 0% to 2%, is aluminum borosilicate glass), alkali glass fiber (sodium oxide 8% to 12%, is boron-containing or non-boron soda lime silicate glass) and high alkali glass fiber (sodium oxide 13% or more, is soda lime silicate glass).

Glass Fiber test range.

Glass fiber cloth, glass fiber screen, glass fiber board, glass fiber tube, glass fiber cotton, glass fiber yarn, glass fiber mesh, glass fiber tape, glass fiber wire, glass fiber mesh cloth, glass fiber felt, glass fiber products, glass fiber pole, glass fiber blanket, etc.

Testing items of Glass Fiber.

Composition analysis, ignition point detection, appearance, quality per unit area, physical property testing, tensile breaking strength, soluble harmful substances, density, ash, content testing, formaldehyde emission, quality testing, chemical property testing, etc.
