PES - PA - PP

Polyester (PES) :

most durable of the common materials
high strength, both wet and dry
good resistance against external abrasion
does not lose strength rapidly due to cyclic loading
low coefficient of friction allows it to slide easily around bitts.
relatively high melting point (256°C) reduces the chances of fusion.

Polyester is therefore useful for large and small rope material where strength and durability are important and where moderate elasticity is required.

Polyamide (PA) :

rope loses 10 – 15% of its strength when wet
highest elasticity of regularly used materials
good temperature and abrasion resistance

Its high elongation characteristics makes polyamide ideal for applications where shock loading occurs, such as mooring tails.

Polypropylene (PP) :

approximately same elasticity as polyester rope
limited temperature resistance
poor cyclic loading characteristics
prolonged exposure to the sun’s ultraviolet rays can cause polypropylene fibres to disintegrate due to actinic degradation
lighter than water

Polypropylene ropes can be used for floating messenger lines. The use of moorings manufactured from 100% polypropylene is not recommended. However, suitable composites or melt mixes with other fibres such as polyethylene or polyester are available and acceptable for use as moorings.

Bexcoline

Our Bexcoline ropes are the result of our special extrusion technology and are made of highly abrasion resistant yarns. A special marine finish is applied to further increase the wear resistance in a marine environment. This finish has been tested conform ASTM D6611-00 and is water repellent.

- Very high strengths comparable to nylon and polyester for much lower weights
- UV stabilized
- Very good abrasion resistance
- Excellent fatigue characteristics
- The rope does not absorb water
- Wet and dry strength are identical.
- Excellent handling characteristics due to the very high strength per weight ratio.
- The ropes conform to INTERTANKO and OCIMF guidelines for tanker moorings.

Depending on the specific requirements of the customer, we can offer different types of composite ropes :

Bexcord (specific gravity of 0.91) is a melted mix of polypropylene and polyethylene and thus 100% floating. The ropes offer a better abrasion resistance and have a much higher strength than standard polypropylene ropes.
BexcoFloat (specific gravity of 0.99) and BexcoFlex (specific gravity of 1.1) are produced with polyester fibres covering a polyolefin core. The polyester fibre is giving the rope a superior abrasion and friction resistance due to its higher working and melting temperature. Our BexcoFlex is not only used as mooring rope, but is also most suitable to be used as a tail, as a superior alternative to the traditional nylon tails.

DYNEEMA®

Dyneema® is a High Modulus PolyEthylene (HMPE) fibre offering maximum strength combined with a minimum weight :
- highest strength per weight ratio
- very good abrasion resistance
- excellent fatigue properties (the lifetime in cycling over sheaves is extraordinary)
- good resistance to axial compression.
- low stretch characteristics.
- limited temperature resistance (melting temperature of 150°C and
- maximum working temperature of 65ºC)
- fibre density of 0.97 : floating

Low stretch ropes are advantageous where limited movement is required, such as at berths with hard arm equipment and where low dynamic loads are expected.
Ropes with Dyneema® are particularly recommended for quick and safe mooring and towing and in some offshore and industrial applications where weight and easy handling are an issue.
They are also used in various applications in commercial fishery, like net panels, cod ends, warp lines, but is also an excellent material for selectivity panels resulting in a strongly decreased bycatch.
