Coppa 3000 is a high tech crossover double braid.
The Coppa 3000 cover is a 16-plait combination of soft PES staple fiber and XLF. It is readily spliceable, and easy to handle. The staple fiber makes this rope super grippy.
Coppa 3000's 12-strand core of Dyneema SK78 ensures maximum breaking strength, low stretch, and minimal creep.
Heavy on the technical side...
Dynema® is the Dutch company DSM Dyneema's brand of UHMWPE (Ultra High Molecular Weight PolyEthylene fiber), a long chain, high strength, oriented strand, synthetic fiber with very high strength as well as high abrasion resistance.
This fiber is also known as HMPE (High Modulus PolyEthylene).
Dyneema is available in a number of formulations, SK-60, SK-75, SK-78, SK-90, etc. Each progressively stronger and more expensive.
Of particular interest these days is the difference between Dyneema SK75 and SK78. Dyneema SK78 has the same high strength of SK75, but with lower creep (non-recoverable stretch).
Honeywell International produces a similar UHMWPE fiber, marketed as Spectra®
