Drift Series

Drift-PP

Name: Drift-PP
Brand: Ropebraiders

It floats, it's cheap, and that is exactly the specification.

8-Strand PlaitedPolypropylene Splice 100%

Schematic — Four pairs, plaited

8-strand plaited polypropylene multifilament. Buoyant and cheap, for lines that must stay out of a propeller: pick-up lines, buoy pendants, barrier and boom rope.

When to specify this

Not a structural fibre. Specify it where buoyancy and cost govern. For load-bearing work, use Surge-8 or Apex-12.

Engineering notes

Specific gravity 0.91. Floats indefinitely
Torque-balanced plait, coils flat and runs free
High-visibility colours as standard for surface work
Lowest cost per foot in the catalogue

Typical applications

Specifications

Minimum break strength is the value we publish and test to — not an average, and not a working load. Divide by your design factor before putting a number on a drawing.

Drift-PP specifications by nominal diameter
Diameter	Min. break strength (lb)	Weight (lb/100 ft)	Working load @ 5:1
1/2"	3,800	4.7	760 lb
5/8"	5,800	7.3	1,160 lb
3/4"	8,200	10.4	1,640 lb
1"	14,000	18	2,800 lb
1-1/4"	21,000	28	4,200 lb

Working load shown at a 5:1 design factor for illustration only. Use the load calculator to apply the design factor, sling angle and termination efficiency your application actually requires.

Weights are nominal and vary ±5% with finish and coating. Elongation measured on new rope after bedding-in; expect higher values on the first cycle. Splice efficiency assumes a correctly made splice with the specified bury length.

Load against elongation

Measured to 30% of MBS. Beyond that the curve is extrapolated from the fibre, and drawn dashed to say so.

Load vs. elongation

Drift-PP — stretch under load

Elongation as a percentage of original length, plotted against load as a percentage of minimum break strength. Drag, or focus the plot and use the arrow keys, to read any point off the curve.

Elongation: 12 %
Load: 30 % MBS
Stretch / 100 ft: 144 in
Source: Measured

Solid — measured at 10, 20 and 30% of minimum break strength, interpolated with a monotone cubic so the fit cannot overshoot.
Dashed — extrapolated to 18% using published Polypropylene elongation at break. Inferred, not measured. Do not design to it.
Shaded — working load at a 5:1 design factor, i.e. up to 20% of MBS.

Drift-PP load against elongation. Load is a percentage of minimum break strength; elongation is a percentage of original length.
Load (% of MBS)	Elongation (%)	Source
0	0	Origin
10	4.2	Measured
20	8	Measured
30	12	Measured
100 (break)	18	Extrapolated from Polypropylene elongation at break

Strength to weight

Break strength per pound of rope, across the catalogue. This is the number that decides what a two-person crew can rig.

Strength-to-weight

12 ropes, ranked highest first

STRENGTH-TO-WEIGHT — LB PER LB/100 FT

Break strength divided by weight per 100 ft, best size in each range. Numerically this is breaking length in hundreds of feet — the length of rope whose own weight equals its break strength.

Strength-to-weight by product, highest first, in lb per lb/100 ft.
