FRP rods GRP rods and water blocking tapes supplier in USA High-performance FRP rods and GRP rods by PolyRods for optical fiber cable strength and durability

Fibre Reinforced Plastic Rod
(FRP/ GRP)

Our GRP Rod are produced from Quality Glass Fibre with an Epoxy Resin. It is used as a Central Strength member or used in Embedding during Fiber Optic Cable Manufacturing. EAA coated GRP provide stronger adhesion to cable jacketing material.

  • Higher tensile strength, High modulus, high flexibility
  • Increase cable protection.
  • Free from chemical corrosion.
  • Low expansion, low weight, Low heat conductivity, cost effective

Water Blocking (FRP ROD)

Water Blocking FRP materials are used in order to immobilize the product and assure the right cushioning, covers all voids in the cable core at the block and prevents flow of water towards the joints. FRP is used for any type of cable specially designed against water ingress, offering protection beyond the water-resistant property of cable jacket.

Various coating available of FRP Rods as per application.

Our FRP Rods are ROHS Complied as per 2011/65/EU & (EU) 2015/863 directive and REACH Complied as per (EC)No.1907/2006 (REACH)

Flat FRP GRP products for fiber optic cable and industrial applications

Flat FRP

Flat FRP are manufactured to serve as dielectric armour in FOC intended for challenging environments. This are used for various cable types, including rodent resistant, direct burial, and bullet resistant aerial cables. Flat rods provide peripheral reinforcement in FOC application and can be embedded in the cable's jacket longitudinally or helically stranded over the core depending on specific design and requirements of the cables.

  • Anti-rodent resistant
  • Helical application
  • Excellent tensile strength
  • Customised dimensions

Purpose of Flat FRP

A standard way to protect fiber optic cables is to use flat, rigid glass-fiber reinforced polymer (FRP) embedded within the cable structure itself. These FRP components serve as strength members, providing essential support and protection without adding significant weight or bulk to the cable design.

ARAMID REINFORCED PLASTIC ROD (ARP)

ARAMID REINFORCED PLASTIC ROD (ARP)

Polyrod is a specialist ARP rod manufacturer in India, producing Aramid Reinforced Plastic (ARP) Rod - a lightweight, high-strength reinforcing member designed for use in Optical Fiber Cables (OFC). ARP Rod combines the excellent tensile strength of aramid fibres with a polymer matrix to provide mechanical reinforcement while maintaining flexibility and low weight, giving cable manufacturers a strength member that performs where conventional glass-fibre rod is too heavy or too rigid for the design.
As a trusted Aramid Reinforced Plastic Rod supplier, our ARP Rod helps provide tensile strength, dimensional stability and protection against mechanical stresses during cable manufacturing, installation and service. Its lightweight construction makes it suitable for compact, high-fiber-count cable designs where space and weight are important considerations - a growing requirement as OFC networks move toward smaller, denser cable builds.
