For those looking for high-quality lifting products, double braid polyester rope is a popular choice and one to consider for many applications. The material polyester offers a combination of strength, durability, and minimal stretch. An experienced wire rope and sling company can offer you this type of polyester rope to help you meet the demands of your lifting applications.
Properties
This type of double braid rope has excellent strength. Polyester itself is measurably stronger than nylon. It has a tensile strength that is in the range of that provided by Nylon 6. Polyester does not stretch too much enabling it to be used effectively for lifting applications. There is a pre-stretching process that occurs during the manufacture of polyester that keeps its stretch to a minimum as a usable product.
With a low level of creep underneath a load, polyester sustains its strength under wet conditions and has a 240°C high melting point. The material loses very little of its breaking strength even after a couple years of use outside – only about 10%. These ropes are highly abrasion resistant and are not conductors of electricity. The material does not absorb water, but is not designated for use in water. It will sink.
Resistance to Chemicals
Double braid polyester rope offers solid chemical resistance. It can resist alkalis and acids at room temperature. As temperatures rise, the resistance of the rope decreases. Polyester also offers excellent resistance to bleaches, solvents, and petroleum based products. The rope should not be soaked in strong bleach for extended periods of time as it can potentially reduce the strength of the material.
Applications
Polyester rope can be used for a variety of applications, including winches, block and tackles, and capstans to name only a few. Safe loading capacity of this type of rope must be understood and evaluated properly according to applicable loading charts or other engineering information. It is important to understand that the indicated strength of rope can be weakened through age, wear and tear, and knots.
By contacting a reliable wire rope sling provider, you can get the guidance you need on double braid polyester rope and other lifting products.
