Materials used in Nautilus Braids

Polyester Double braid

Most of Nautilus Braid's ropes are made from high tenacity continuously spun multi-filament PE (polyester) or P.A. (Nylon) having a tenacity of around 8 gms per denier. Some special “buoyant” ropes use PP (polypropylene because of it's especially low density)

We also carry new age fibre like Dyneema/Spectra (UHDPE - ultra high density polyethylene) and Vectran (polyarylate superfiber).

 

Dyneema® (UHMWPE)

Dyneema® (Dyneema on Wiki) is a highly advanced range of products based on an ultra-high molecular weight polyethylene (UHMWPE). It is incredibly strong—15 times stronger than steel. Yet it’s extremely lightweight—up to 40% lighter than materials like aramids. Patented technologies give Dyneema® its unique, highly-directional attributes that allow for its unmatched strength-to-weight ratio.

VECTRAN™

Vectran (Vectran on Wiki) is a high-performance multifilament yarn spun from liquid crystal polymer (LCP). Vectran is the only commercially available melt spun LCP fiber in the world. Vectran® fiber exhibits exceptional strength and rigidity. Pound for pound Vectran fiber is five times stronger than steel and ten times stronger than aluminum.
