UHMWPEPARA-ARAMID 03 / 09

Ropes and slings

High load at lower weight

UHMWPE S series and low-creep LC grades are intended for mooring, towing, rigging and deep-water systems. Para-aramid is considered where heat resistance is also important.

01 — ROLE IN THE PRODUCT

How each material works

The material is selected by its function in the structure. The same product may require different fibres depending on the environment and load.

UHMWPE

Marine and highly loaded ropes

S series is intended for ropes and nets; LC series for systems where creep, fatigue and long service are especially important.

PARA-ARAMID

Heat-resistant industrial solutions

Filament yarn is used in ropes and strength members where heat and abrasion resistance are required alongside strength.

02 — APPLICATIONS

Where the yarn is used

A

Mooring and towing

Lightweight high-strength lines for ships and port operations.

B

Slings and rigging

Lifting and pulling systems with high specific strength.

C

Deep-water systems

Low-creep solutions for sustained loads and marine environments.

D

Industrial ropes

Safety, rescue and special constructions after assessment of operating conditions.

Supply forms and series

A starting point for a technical inquiry, not a ready-made pilot specification.

UHMWPE
  • S: 800 / 1000 / 1500 / 1600 / 3000D
  • LC: 1600LC2 / 1600LC3
  • Overall yarn range up to 4800D
  • Construction and filament count according to TDS
PARA-ARAMID
  • Filament yarn 220–3340 dtex
  • 1110/1670 dtex options with different filament counts
  • Selected by load, elongation and temperature

What the material offers

  • High strength at low weight
  • UHMWPE floats and resists seawater
  • LC series is designed to reduce creep
  • Para-aramid extends the temperature range

Mandatory checks

  • Rope breaking load is not equal to yarn strength
  • Splices, knots and bends reduce construction efficiency
  • Creep must be assessed separately for sustained loads
  • Lifting safety is confirmed by tests on the finished product

05 — SELECTION AND PILOT

Four inputs for a technical inquiry

The more precise the inputs, the fewer unnecessary samples and the faster the comparison with the incumbent material.

LoadWorking, breaking, shock and sustained load
ConstructionBraid, diameter, splice, coating and weight
EnvironmentSeawater, UV, abrasion, temperature and chemicals
DynamicsBending over rollers, fatigue, creep and cycles
