impossible to make blanket recommendations as to the correct choice of rope to use. However, we have provided the tensile strength for each diameter and type of rope. These strengths are based on tests of new and unused rope, with appropriate splices. Proper choice, care and inspection of the rope are essential for reasonably safe use of the rope.

Polypropylene is considered one of the most versatile types of plastic. We often come across this material at home in kitchen utensils, athletic wear, and decorative rugs. Polypropylene’s characteristics make it ideal for a wide range of tough products, such as microwaveable containers, car bumpers, and medical tools.
Polypropylene rope is a great general-purpose material for domestic or business purposes. This type of rope is rot-proof, floats in water, and has a high melting point. It also comes in many sizes and bright colors. Given these advantages, polypropylene is the natural choice for water use. It doesn’t splinter easily and can increase visibility in l...
Polypropylene rope is stiff and slippery and can easily become undone. There are certain types of knots that work well with this material. And even if it's a synthetic rope with a high melting point, it can be severely damaged by prolonged exposure to extreme heat and UV. It will become discolored and frayed when left under the sun for too long.

Manila is extracted from the tropical abaca plant, native to the Philippines. It is the strongest of all natural fibers used in rope-making. All rope has a breaking point. But unlike synthetic ropes, manila ropes don’t snap under heavy loads, which can be a safety hazard. They merely begin to fray. Manila rope is flexible and easy to tie into ...
Nylon will last 4-5 times longer than natural fibers. JUTE is mainly used as a tying twine. It knots very well. Due to its short fibers, it does not have much strength. COTTON is natural fiber, typically white in color. It is a soft fiber, which makes it nice to handle. It also knots very well. Rope Selection Guide FIBER TYPE NYLON POLYESTER ...
fibers, long term exposure to UV shows the lowest decrease in strength and elongation at break. Fungal resistance. Dyneema® fiber has excellent biological resistance. The fiber neither stimulates undesired growth nor is sensitive to any attack by micro-organisms. Toxicity. Polyethylene is regarded as biologically inert. The
Tensile strength is the load at which a new rope, tested under laboratory conditions, can be expected to break. Rope strength is the approximate average for new rope tested under ASTM test method D-6268. To estimate the minimum tensile strength of a new rope, reduce the approximate average by 20%. Age, usage, and type of termination used
fiber core rope and over 90% of the strength of a typical 6-strand wire rope with an independent wire rope core. Properties like fatigue resistance and resistance to abrasion are directly affected by the design of strands. In most strands with two or more layers of wires, inner layers support outer layers in such a manner
