While synthetic rope has a higher breaking strength than similar steel cable, it is not indestructible. Unlike steel cable, however, if a synthetic line breaks, it can be mended in the field using suitable braiding procedures. Rope materials include nylon, polyester, and polypropylene.
Synthetic ropes are generally more resistant to damage from heat and chemicals as well as high loads than cables. This means that they are better choices for applications where exposure to these elements is likely. For example, synthetic ropes are commonly used by farmers to lift heavy loads into and out of their vehicles because they are not as affected by heat or cold as metal cables would be.
Cables have the advantage of being reusable if care is taken not to stretch them too much. They will also last longer if not used often because there is less chance of corrosion affecting the metal wires within.
Ropes come in various strengths depending on the type of material it is made from. Synthetic lines tend to be more flexible but less strong than steel wire. They are therefore useful for low-load applications such as fencing or pet leads where maximum flexibility is required.
Steel cable is the strongest option available and the most durable. It is usually used for lifting heavy loads and for securing objects permanently because it will not break under stress like plastic or rubber cords might.
Because of the way the synthetic material stores energy, synthetic rope is intrinsically safer than steel rope. These ropes are significantly less likely to shatter than cable, and even if they do, the energy stored is so little that the effects are modest, and harm or damage is improbable. Synthetic rope does, however, have its limitations. It will not brake as sharply as steel rope, so it should be used with caution when fastening down equipment such as trees or heavy objects.
Synthetic cables are made from polyethylene terephthalate (PET) film or fiberglass. They are non-conductive, lightweight, strong, and relatively inexpensive. The main disadvantage of synthetic cables is their lack of durability. They can get old and brittle over time, which can lead to a loss of strength.
Steel cables are made from metal wire or rod that is then twisted or woven into a cord. They are conductive, which means they have the ability to transmit electricity, but this feature comes at a price: steel cables are heavier than their synthetic counterparts and more likely to break if overloaded. They will also tarnish with use and require regular maintenance to keep them working properly.
The choice between steel and synthetic cables really depends on how you plan to use your winch and what kind of environment you will be operating in.
Synthetic rope is substantially lighter and simpler to handle than steel cable. This has made it a popular destination for both professional tow truck operators and recreational off-road enthusiasts. Though synthetic rope offers obvious advantages, it is not widely accepted. Critics say it isn't as strong as steel cable.
The first modern-day polyester fiber was developed by Dr. Edwin Land in 1938. He called this new material "cellophane" because of its translucent quality. In 1951, General Electric introduced the world to nylon - a plastic formed into fibers that are stronger than silk but more flexible than steel. Nylon's popularity quickly grew due to its strength-to-weight ratio and its ability to withstand repeated washings without losing color or shape. Today, hundreds of different types of synthetic fibers are used to make clothing, ropes, and other products that would have been unthinkable just a few decades ago.
Synthetic materials have many benefits for outdoor use. They are resistant to heat, cold, and water, which makes them perfect for use as tethers, anchor lines, and rappelling devices.
One major disadvantage of synthetic rope is its cost. For many applications, such as mountain biking, it is not feasible to use synthetic rope because of its exorbitant price. Steel cable remains the standard against which all other tethers are measured. It is affordable, durable, and reliable.
Synthetic rope is eight times lighter than wire rope, eliminating the need for physical handling. Wire rope is heavier and more difficult to move than synthetic rope. The longevity of your rope will be affected by how it is handled and cared for, depending on the use. Synthetic ropes have a longer life in general because they are not as physically demanding to handle.
Wire ropes may experience some wear due to physical handling and use. This can lead to corrosion of the metal core which can then be felt as a rough touch when handling the rope. This type of damage should be taken into account when selecting an anchorage point for a line. If possible, avoid tying off to cleats or other protruding objects that could damage the rope.
Synthetic ropes are used in many common applications including for climbing purposes, rappelling, and rescue operations. They can be tied off securely with standard knots such as the bowline or figure-eight.
Wire ropes are usually only used for heavy duty applications where the weight of the rope is sufficient to maintain its shape and prevent corrosion. These include scaffolding, hoists, and crane rigging.
Both types of rope can be damaged by exposure to heat or sunlight. This can cause the plastic coating to melt or peel away, leaving the core material exposed.
