Core Features

1. High tensile strength and low elongation. Its strength is close to steel while it weighs less. It has an extremely low elongation at break and small deformation under force, which can effectively bear tensile force and protect the optical cable structure from tensile damage. It is the main raw material for FRP glass fiber rods.

2. Excellent electrical insulation performance. Adopting an alkali-free formulation, it features stable dielectric properties and high insulation resistance. It is non-conductive and free of electromagnetic induction, so it will not interfere with optical signal transmission, making it suitable for reinforcing communication cables and optical-electric composite cables.

3. High temperature resistance and good thermal stability. It has a high softening point and can withstand high-temperature extrusion processes for a short time. It has a low coefficient of thermal expansion with tiny dimensional changes under high and low temperature environments, keeping the optical cable structure stable under alternating temperature working conditions.

4. Aging resistance and corrosion resistance. It resists acid, alkali, salt spray and microbial erosion and will not rust. Its performance degrades slowly during long-term service in underground and humid coastal environments.

5. Good wettability with resins. Its surface is treated with coupling agent, delivering strong bonding force when wetted with epoxy resin and unsaturated resin. Delamination rarely occurs during the pultrusion of FRP rods, and the mechanical properties of finished products remain stable.

6. Flame retardant and non-combustible. As an inorganic non-metallic material, it cannot burn and releases no toxic flue gas, compatible with various flame-retardant optical cable systems.
