Properties of Fiberglass Fabrics
Fiberglass textile fabrics will not rot, mildew or deteriorate. They resist most acids with the exceptions of hydrofluoric acid and phosphoric acid.
Fiberglass fabrics will not stretch or shrink. Nominal elongation break is 3-4 percent. The average linear thermal expansion coefficient of “E” glass is 5.4 by 10.6 cm/cm/°C.
GOOD THERMAL PROPERTIES
Fiberglass fabrics have a low coefficient of thermal expansion and relatively high thermal conductivity. Glass fabrics will dissipate heat more rapidly than asbestos or organic fibers.
HIGH TENSILE STRENGTH
Fiberglass yarn has a high strength-to-weight ratio. Fiberglass yarn is twice as strong as steel wire.
HIGH THERMAL ENDURANCE
Fiberglass cannot burn and is basically unaffected by curing temperatures used industrial processing. Fiberglass will retain approximately 50 percent of its strength at 700°F and as much as 25 percent at 1000°F.
LOW MOISTURE ABSORPTION
Fiberglass yarn has extremely low moisture absorption.
High dielectrical strength and relatively low dielectrical constants make fiberglass fabrics outstanding for electrical insulation purposes.
The wide range of filaments, fiberglass yarns, yarn sizes, weave types and finishes make fiberglass fabrics available for a broad range of industrial end uses
Fiberglass fabrics offer cost advantages compared to other synthetic and natural fiber fabrics.
