Reliable, Insulated and Corrosion-resistant FRP fasteners

FRP (Fiber Reinforced Plastic) insulated fasteners are a type of connector that combines reliable mechanical fastening with excellent electrical insulation performance. They fix components while blocking current flow between parts with different potentials, preventing leakage, short circuits, grounding faults, and current interference. The key distinction from ordinary metal fasteners lies in their non-conductive and strong dielectric properties.FRP fasteners typically include bolts, nuts, studs and washers.

Main FRP fastener Materials

Epoxy-based FRP is the most widely used and highest-performing type, featuring high strength, dimensional stability, excellent insulation, and superior temperature resistance, making it ideal for power, industrial, and high-end corrosion-resistant applications.

Unsaturated polyester FRP, with low cost and excellent weather resistance, is widely used in general corrosion protection, construction, and wastewater treatment.

Carbon fiber reinforced CFRP (CFRP) is characterized by ultra-high strength, high modulus, and high cost, making it ideal for precision and lightweight applications.

Characteristics of FRP Fasteners

Heat-resistant: High-strength insulating fasteners can withstand high-temperature environments, ensuring reliable operation under extreme conditions.

Excellent insulation performance: This fastener's insulation effectively prevents current leakage, ensuring equipment safety.

Corrosion resistance: Engineered with specialized materials, these high-strength insulating fasteners are designed to withstand corrosion from various chemicals.

High tensile strength: Compared to thermoplastic materials, FRP fasteners exhibit six times greater tensile strength.

Lightweight: With a density of 1.9 t 2 g/cm³, it weighs only about 1/4 as much as steel of the same volume.

FRP (Fiber Reinforced Plastic) insulating fasteners are widely used in power systems (insulation fixation in transformers and generator ), chemical corrosion protection equipment, water treatment facilities, marine engineering, environmental systems, and electronic communications. They serve as metal fasteners to effectively address the challenges of electrical insulation and corrosion.
