Fiberglass Properties
- Jul 18, 2018 -

Melting point:Glass is an amorphous type. It has no fixed melting point. It is generally considered to have a softening point of 500~750 °C.

Boiling point:1000 °C


When glass fiber is used as a reinforcing material for reinforced plastics, the biggest feature is the high tensile strength. The tensile strength is 6.3 to 6.9 g/d in the standard state and 5.4 to 5.8 g/d in the wet state. The density is 2.54 g/cm3. Good heat resistance, no effect on strength when the temperature reaches 300 °C. It has excellent electrical insulation and is an advanced electrical insulating material. It is also used for thermal insulation materials and fireproof shielding materials. Generally only corroded by concentrated alkali, hydrofluoric acid and concentrated phosphoric acid.
