Key fiberglass properties
- Chemical resistance
- Inorganic glass fibers resist rot, mildew, and most acids. Hydrofluoric acid and hot phosphoric acid are exceptions.
- Dimensional stability
- Glass yarns resist atmospheric stretching and shrinkage. Nominal elongation at break is 3 to 4%.
- Thermal properties
- Low thermal expansion and relatively high thermal conductivity help glass fabrics dissipate heat.
- Tensile strength
- A high strength-to-weight ratio supports unidirectional or bidirectional fabric design.
- Thermal endurance
- Inorganic glass fibers do not burn and withstand industrial baking and curing temperatures.
- Low moisture absorption
- Noncellular glass fibers absorb very little moisture.
- Electrical insulation
- High dielectric strength, low water absorption, and temperature resistance support electrical insulation.
- Product flexibility
- Yarn sizes, weave types, and finishes accommodate many industrial applications.
- Cost
- Glass fabrics compare favorably in cost with synthetic and natural fiber fabrics.
Fabric selection
Consider thickness, weight, construction, yarn size, and finish. Consult a JPS technical or sales representative before choosing a fabric for your application.
