ARP Rod - Aramid Reinforced Plastic Rod Manufacturers and
Suppliers in India

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.

Key Benefits:

  • High tensile strength with low weight
  • Excellent flexibility and bending performance
  • Provides mechanical reinforcement to OFC
  • Suitable for compact and high-density cable designs
  • Good dimensional stability
  • Easy to process during cable manufacturing
  • Available in different sizes and specifications as per cable design requirements

As a specialist fiber optic cable raw material supplier, our ARP Rod serves as a central strength member for optical fiber cables - particularly in applications like ADSS aerial cables, micro-duct and high-fiber-count cables, and other compact, lightweight cable designs where minimising weight and maximising flexibility alongside strength is the priority.

FAQs

Frequently Asked Questions

1. What is ARP rod made of?

ARP (Aramid Reinforced Plastic) rod is made from high-strength aramid fibre impregnated with resin, giving it roughly 68% aramid content by weight - a different raw material from the glass fibre used in standard FRP/GRP rod.

2. How is ARP rod different from FRP/GRP rod?

ARP rod uses aramid fibre instead of glass fibre, giving it a much higher tensile strength (≥1500 MPa) and tensile modulus (≥65 GPa) at a lower weight than glass-fibre FRP/GRP rod, making it better suited to lightweight, long-span or high-flex cable designs.

3. What cable types is ARP rod used in?

ARP rod is commonly used as a central strength member in aerial self-supporting (ADSS) cables, micro-duct cables, and other fiber optic cable designs where reducing weight and maximising flexibility alongside strength is important.

4. Is ARP rod available with a coating?

Yes, ARP rod can be supplied with an EAA coating (40 ± 20 microns) as per customer requirement, for improved adhesion to the cable jacket material.

5. Can ARP rod be supplied in custom lengths for bulk orders?

Yes, ARP rod is supplied in lengths as per customer requirement, spooled for direct use on cable production lines, and is available for bulk and export orders including supply from India to the USA.
