PE - Staple Rope is soft on
the hand, easy to handle and flexible. It's hairs
on the surface make good grip at the hand.
High ultra-violet stabilization
Applications are
fish-farming, lashing, anchor rope
and general purpose.
|
 |
Polypropylene rope has nearly
twice the strength of Manila rope when compared
size to size. The rope has positive buoyancy (floats)
and doesn't absorb water, rot or decay. It is resistance
to acid, alkali and most chemicals. When
not in
|
 |
|
use the rope should be stored away from direct sunlight.
Recommended usages are mooring, dock and anchor
line, boat life-line, tarpaulin line, tent tie-down,
pool barrier line, public utility and general use
in home, farm and industry. |

Advanced Durability
Excellent anti-abrasion properties contribute to a long working
life (Over 10% when compared to standard ropes) and high UV
light resistance.
Super Strength |
 |
Nylon rope exceeds twice the strength of Manila. It has high
elongation (underload) when compared to other synthetic ropes.
Nylon has high energy absorption under shock and good abrasion
resistance. |
 |
| |
50% better
breaking strength compared to BS
and ISO standards and specifications and a cost effective super
strength rope.
Variety of Applications
A multi purpose rope ideal for general industrial
& commercial fishing applications and an excellent rope
for deep sea pot rope use.
SUPERDAN 3 Strand & SUPERDAN 8 Plait Mooring Rope available
|
When combined,
these characteristics
make nylon rope the best handling compared to other synthetics.
It is utilized in marine use such
as mooring lines, towing slings, commercial
fishing, utility rope, leisure and sailing. |

Polyethylene rope has positive buoyancy (floats) but is slightly
heavier than polypropylene rope. Tensile strength remains the
same dry or wet. Commonly used in commercial fishing and industrial
applications. |
 |
Lead Core rope is manufactured from fibre wrapped lead lines
so as to make the rope heavy manila rope. Lead Core ropes are
used in commercial fishing, particularly as net bottom lines.

DYNAMICA rope is made from Dyneema fibres produced in Holland.
Dyneema is one of the strongest fibres in the world. The rope
has excellent properties with regard to strength, weight, UV-stability
(daylight), safety, abrasion, tension fatigue, bending fatigue.
DYNAMICA rope is the most compact Dyneema rope in the world.
DYNAMICA rope is produced in Denmark on state of the art machinery,
to ensure the best obtainable quality. It is coated with a unique
coating that ensures shape stability and increased abrasion
resistance for longer working-life. DYNAMICA rope is heat-set
under tension to ensure maximum strength, durability and uniformity.

Dyneema Fibre Properties - Strength
Dyneema is more than ten times stronger than steel per
unit of weight. This means that a Dyneema rope has a slightly
higher strength than a steel wire of the same dimension -
but less than one tenth of the weight.
Dyneema Fibre Properties - Tension-tension fatigue
Dyneema can sustain a very large number of peak loads (loads
close to the breaking strength). This gives a long life and
a high safe-working load. While steel-wire can take 6500 loads
at 50 % of the maximum breaking load a DYNAMICA rope can take
10 million cycles at the same load level. DYNAMICA rope is
therefore an excellent material for dynamic applications.
Dyneema Fibre Properties - Safety
Dyneema has a very low elongation (2-3% at break). It stores
little energy and has therefore little backlash - even at
hundreds of tonnes of load. This is a very important safety-feature.
Dyneema Fibre Properties - UV-stability
Dyneema has a better stability to sunlight than other relevant
fibres. After two years of exposure 80% of the strength is
retained.
Dyneema Fibre Properties - Resistance to chemical substances
Dyneema is resistant to chemical substances and will not be
affected by oil acids or other substances.
Dyneema Fibre Properties - Abrasion
Dyneema has an excellent abrasion resistance compared with
other synthetic fibres (five times better than polyester).
Special care has to be taken, however, in order to ensure
that it moves over clean non-rusty surfaces etc. Sharp edges
etc. should be avoided.
Dyneema Fibre Properties - Bending-bending fatigue
Dyneema has good bending-bending properties. However it is
recommended to bend over diameters of at least five times
the diameter of the rope.
Applications
Offshore applications, Fisheries (Bridels, Gilson lines,
seam lines, front end meshes), Lifting applications
Mooring, Towing
