Specific Gravity - .97 Melt Point - 144-152° Tenacity - 30gpd
Dyneema® Fiber is one of the more common high performance fibres available on the market. Its high strength and low elongation and light weight make it the ideal braid for sheets, guys and control lines. It has excellent chemical resistance and UV resistance, although it tends to have a cover over the dyneema core, generally polyester, to increase its working life. The Dyneema® SK75, SK78 and SK90 yarn is the strongest fibre in our current range. Negatives in using dyneema are the slippery nature of the fibre and the tendency to creep, i.e. elongation under a prolonged load.
Specific Gravity 1.41 Melt Point - 330° Tenacity - 23gpd
Vectran™ is a high performance fibre that is specifically designed for fixed load applications. It has a very high melting point and can withstand extreme temperatures, its high strength, low elongation and very low creep makes it ideal for Halyards. It has excellent cut resistance and has low moisture absorption. Its U.V stability is poor, however its abrasion and cut resistance is much superior to polyester and it is used in extreme performance yacht braid covers
Specific Gravity Melt Point -144°-152°
Dynex™ is a urethane coated heat set Dyneema or Spectra core and can come in a variety of urethane colours. With the urethane coating Dynex™ has excellent U.V, abrasion resistance and very low elongation. It has excellent tension and bending fatigue surpassing that of steel at common working loads. Its high strength and low weight make it suitable for ropes used in yachting applications halyards, sheets or any other application where a high performance rope is needed. It is often used with an outer cover, normally polyester, to extend its working life. Although it is heat set, it does still creep under extended load.
Specific Gravity - 1.38 Melt Point - 260°c Tenacity - 8.5gpd
Polyester is the most commonly used material in our range. It is also available in a wide range of colours and weights, the most common weights are 250, 500, 1000 & 1500 denier. It is resistant to U/V rays and all colours are colourfast. Prolonged exposure in water has little or no lasting effects. It has good abrasion resistance, especially when twisted. However it can not be dyed using normal dyeing methods. It has low stretch and used in all 5 & 6 series, sash cords, luff cords, HJ series and yacht braids; it is suitable for Halyards, Sheets, Reefing lines and control lines on cruising boats.
Specific Gravity - .91 Melt Point - 165° Tenacity - 7.8gpd
Polypropylene is a light weight material that is used throughout the marine industry for rescue lines and anything else that requires a light weight floating rope. Its abrasion resistance is not equal to polyester and other yarns but it is U/V stabilised. It has excellent chemical resistance and does not retain water. It is good as a multi-purpose rope but loses strength under heavy shock loads, it can be used for rescue lines and other general purpose uses.
Specific Gravity - 1.14 Melt Point - 250° Tenacity - 8.9gpd
Nylon has a higher strength than polyester but also has more elongation. It tends to be used for fixed applications such as mooring lines or sea anchors. It has excellent abrasion resistance but tends to harden as the rope gets more worn. It can also be dyed using acid dyes.
Specific Gravity - .95 Melt Point - 135°
Used in monofilament form for easy splicing braids - ie CPE560 - CPE580 It is a light weight rope that floats and is used for general purpose ropes such as safety lines and anything else that require a floating line.
Specific Gravity -1.44 Melt Point -Chars at +450°
The original high tech fibre, it has exceptional strength for a low weight fibre that can be up to 5 times stronger than steel on an equal weight basis. Kevlar is extremely heat resistant and has exceptional cut resistance; it is used in bullet proof vests for this reason. It is un-affected by water and is also used in the construction of mooring lines and elevator cables. It has little creep and low elongation and is best kept away from alkaline conditions or exposed to chlorine. The main negatives is poor point loading and poor U.V resistance.
Specific Gravity -1.50 Melt Point -Starts decomposing at 600°
PBO™ is an ultra high strength fibre; it can be used for ultra high performance applications such as America's cup boats, but rarely used in recreational applications because of cost. It is used in fixed applications such as back stays and can also be used as a cover for other high performance braids because of its high heat resistance. It has excellent chemical resistance and is unaffected by submersion in water. It does however tend to have a shorter working life than that of other high performance fibres because it is affected more by sunlight and fatigue.
