Fiberglass is a material consisting of numerous extremely fine fibers of glass. Glass fiber is formed when thin strands of silica-based or other formulation glass is extruded into many fibers with small diameters suitable for textile processing. These are useful because of their high ratio of surface area to weight. However, the increased surface area makes them much more susceptible to chemical attack.
Types of most commonly used fiberglass are as follows:
- E-glass (alumino-borosilicate glass with less than 1 wt% alkali oxides, mainly used for glass-reinforced plastics)
- A-glass (alkali-lime glass with little or no boron oxide)
- E-CR-glass (alumino-lime silicate with less than 1 wt% alkali oxides, has high acid resistance)
- C-glass (alkali-lime glass with high boron oxide content, used for example for glass staple fibers)
- D-glass (borosilicate glass with high dielectric constant)
- R-glass (alumino silicate glass without MgO and CaO with high mechanical requirements)
- S-glass (alumino silicate glass without CaO but with high MgO content with high tensile strength).
In practice we usually have in C- glass and E- glass products.
Application:
Fiberglass cloth is utilized in many industries for a wide range of applications such as insulation, marine and recreational, electronics, filtration, commercial and construction.
