Product Description
3-Strand PET And PP Mixed Rope
Product Introduction:
Our 3‑strand twisted PET (polyester) and PP (polypropylene) mixed rope is a versatile, high‑performance mooring and towing line developed for modern marine and industrial operations. By combining the best attributes of both fibres - polyester’s superior strength and abrasion resistance with polypropylene’s light weight and buoyancy - this hybrid rope delivers an exceptional balance of durability, handling ease, and cost‑effectiveness.
Outstanding Performance & Technical Advantages:
1.High tensile strength with controlled, low elongation - as illustrated in our stress‑elongation comparison chart, the PET/PP mix outperforms pure PP multifilament and nylon (PA6) in modulus retention, offering a lower stretch profile than standard PP while retaining excellent shock absorption. This reduces energy loss during mooring and towing.
2.Excellent abrasion and wear resistance - ensures a long service life even under heavy friction against fairleads, bitts, and rough deck edges.
3.Soft, smooth surface - makes the rope easy to handle, splice, knot, and coil, significantly reducing crew fatigue.
4.Spliced strength loss ≤10% (verified in accordance with ISO 2307), guaranteeing reliable and safe terminations.
5.Weight and length tolerance: ±5%, ensuring consistent quality, simple inventory management, and predictable performance.
6.For hazardous environments (e.g., oil tankers, chemical carriers, or explosive‑risk zones), we can produce anti‑static versions upon request to safely dissipate static charges.

Wide Range of Applications:
This hybrid rope is the preferred choice for a broad spectrum of sectors, including:
*Marine outfitting - mooring, towing, spring lines, and anchor pendants.
*Fishing industry - trawl warps, net hauls, and purse seine lines.
*Port handling - ship‑to‑shore mooring, cargo lashing, and tugboat services.
*Power construction - line pulling, conductor stringing, and temporary supports.
*Petroleum exploration - offshore platform mooring, subsea deployment, and towing of supply vessels.
*Sports equipment - sailing sheets, waterski tow lines, and adventure course ropes.
*National defence & scientific research - specialised towed arrays, field deployment, and rescue systems.
Colour & Customisation:
*Standard colour: White (high visibility and universally accepted).
*Custom colours (e.g., blue, red, orange, yellow, or striped patterns) are available on request for easy identification, fleet branding, or safety coding.
Certifications:
Our ropes are manufactured under strict quality control systems and can be supplied with classification society approval certificates from leading bodies such as DNV, ABS, LR, BV, and CCS upon request. These certifications ensure full compliance with international maritime regulations, port state controls, and insurance underwriter requirements, giving you complete peace of mind.
