FRP Fasteners

FRP fasteners are employed in technical sectors where electrical, chemical, and thermal properties are critical. Glass fibre reinforced epoxy or polyester resin systems with particular additives and a unique structure are used to make FRP fasteners.

FRP fasteners have the following advantages over steel fastening:

  • a lot lighter
  • Insulating both electrically and thermally
  • Corrosion protection
  • Defiant in the face of adversity

Properties of FRP Fasteners

  • ELECTRICAL PROPERTIES: FRP fasteners are non-magnetic and electrically insulating. Furthermore, partial discharge is free to large electric field strengths and is particularly non-tracking. They’re great for transformers, electrical engineering, high-frequency switching, and electrostatic powder coating.
  • CHEMICAL PROPERTIES: FRP fasteners are particularly resistant to strong fluids and gases, as well as transformer oil and dielectric liquids. They are also UV and weather resistant.
  • THERMAL PROPERTIES: When compared to steel (15-58 W/mk), frp threaded rods, bolts, and nuts have a very low thermal conductivity of 0.3 W/mk, which puts them on par with mineral wool, which is used as insulation in construction. They’re perfect for use in refrigeration, HVAC, and other applications where thermal bridges are a concern.
  • COMPOSITE FASTENERS ARE LIGHTWEIGHT: Composite fasteners have a density of 1.9 t 2 g/cm3 and hence weigh about a quarter of the weight of steel. They’re ideal for applications where weight reduction is critical, such as vehicle construction or the fabrication of wind turbine nacelles.
  • HIGH TENSILE STRENGTH: Threaded rods manufactured of thermoplastics, such as polyamide frp, offer a six-fold higher tensile strength than threaded rods made of metal.
