Spectra Ropes: What You Need To Know

Spectra Ropes

Spectra rope is ideal when high strength and low stretch are required, such as in yachting. A UHMWPE core is wrapped in a polyester covering to create Spectra.Honeywell, a US company, created Spectra, a polyethylene fiber made from crude oil, in the 1980s. Aside from being chemical, water, and ultraviolet light resistant, its low weight makes it a potential floating material.

Spectra fiber: what is it?

Honeywell’s Spectra is a technological marvel of fiber. This one-of-a-kind fiber, created in the USA, is almost five times as strong as steel. Spectra Fiber, plastic in the polyethylene family, is notable for its strength, durability, abrasion resistance, and lightweight composition. The S-12 is a 12-stranded Spectra Rope available only from Pelican Rope.

How is Spectra Fiber used to make rope?

Unique to Pelican Rope, the S-12 Rope is made from Spectra Fibers. This 12-strand braided Spectra Cord can withstand water and has high corrosion resistance. It has a remarkable reputation for durability in addition to being chemically, abrasion-, and flex-fatigue resistant.

Pelican Rope’s S-12 features its unique coating for maximum stretch. This great rope may be purchased with tensile strengths between 2,900 and 165,000 pounds and widths between 1/8 inch and 1 14 inches.

Spectra ropes is the way to go when weight and reliability are paramount. Made with a proprietary gel-spinning technique, it is:

  • A chemical, water, and UV light-proof, brilliant white polyethylene fiber
  • It is 40% stronger than aramid fiber and 15 times stronger than steel.
  • Withstanding high strain at high velocities and loads
  • There are fibers available that both DNV and OCIMF have approved.

Spectra ropes has various advantages when used to make rope or cordage:

  • Ropes with a high strength-to-weight ratio are less cumbersome because they weigh less overall.
  • Ropes made using hydrophobic material won’t rot or absorb water.
  • Its inherent buoyancy makes it well-suited for a wide range of marine and offshore applications.

Longer product life and lower maintenance costs due to corrosion, chemicals, abrasion, and fatigue resistance.

Comparison of Dyneema and Spectra Fiber Line

Dyneema’s breaking strength is more vital than Spectra’s and has a slightly different chemical structure. It’s not quite as elastic as Honeywell’s Spectra 1000, but it has better wear characteristics in high-traffic areas. This fiber is becoming more popular in the United States and has already proven to be successful in Europe.

Spectra ropes is an excellent fiber because of its strength and longevity. It stretches very little and is buoyant because of its modest weight. The Spectra fiber has the most extended fatigue life. Spectra’s only fundamental problem is creep. Even when subjected to constant, severe loads, the lengthening rate of Spectra remains low.

Your jib halyard may look an inch looser after some time has passed. Using a size-up will significantly lessen creep. However, it still might be perceptible. Spectra is the best choice for halyards, guys, and sheets on a spinnaker due to its excellent fatigue resistance and low weight. Because it doesn’t get heavy when wet, Spectra is great for boats.

Specifications of Spectra Ropes

UHMPE Spectra rope This one-of-a-kind fiber floats on water, is impervious to ultraviolet light and chemicals, and is strong enough to bear exceptionally high viscos-elastic strain and high-load strain rate velocities.

Definitions of Common Rope Materials

Spectra ropes used to be crafted from various natural materials, including Manila, hemp, and others. They were effective, but superior artificial fibers have since replaced them.

Nylon, polyester, and polypropylene are the three most common types of synthetic fiber. When compared to polyester and polypropylene, nylon is the strongest. Because of its elasticity, nylon is well-suited for shock-loading applications but not for those requiring merely a small degree of stretch.

Polyester’s strength and lack of elasticity make it a versatile material with many possible applications. One significant benefit of polypropylene is its buoyancy. Since a submerged rope could present dangers, this is the best rope to use when painting dinghy sides or mooring pennants.


Ultra-High Molecular Weight Polyethylene fibers, like those found in Spectra, are renowned for their exceptional toughness and longevity. An artificial fiber consists of polyethylene with an extremely high molecular weight. This incredibly robust material has endured the test of time as one of the strongest and lightest fibers on the planet.
