AmSteel Dyneema® AS-78 Single Braid - 52 feet

AmSteel Dyneema® AS-78 Single Braid - 52 feetStrong as steel, very low stretch and so light that it floats. With enhanced creep performance for superior resistance to stretching over time, AS 78 incorporates high performance Dyneema SK 78 into a 12 strand single braid line. Dyneema SK 78 fiber has one of the highest strength to weight ratios of all the high modulus fibers. Very high strength, 30 40% lighter than Aramid ropes of the same strength, is matched with very low weight, and it floats.

Strong as steel, very low stretch and so light that it floats.

With enhanced creep performance for superior resistance to stretching over time, AS-78 incorporates high-performance Dyneema SK-78 into a 12-strand single braid line. Dyneema SK-78 fiber has one of the highest strength-to-weight ratios of all the high-modulus fibers. Very high strength, 30 - 40% lighter than Aramid ropes of the same strength, is matched with very low weight, and it floats.

Its extremely low elongation and outstanding creep performance are matched by excellent flex-fatigue performance and abrasion resistance. It offers the racing community the next generation in high-performance lines and is the same price as Samson's SK-75 single braid. Coated with Samson's proprietary Samthane coating.

Key Features

• Load it to 30% of its breaking strength and it stretches less that 1%
• Much lighter than wire rope, and 30 to 40% lighter than Aramid ropes of the same strength
• Use for cascade systems, replacements for wire halyards, tapered sheets, backstays, runners, checkstays, trapeze lines and strong ultralight rigging
• Add a cover where you need to cleat it or where it runs through a rope clutch
• Very easy to splice with a 12-strand eye splice
• Keep some onboard in a variety of different diameters for emergency repairs and replacements

Specifications

• Construction: 12-strand hollow single braid
• Core fiber: Dyneema® is a brand of UHMWPE (Ultra High Molecular Weight PolyEthylene fiber) from the Dutch company DSM Dyneema. It is a long chain, oriented strand synthetic fiber with very high strength as well as high abrasion resistance, also known as HMPE (High Modulus PolyEthylene). Dyneema rope is made in a number of formulations, SK-60, SK-75, SK-78, SK-90, etc. Each is progressively stronger and more costly. Honeywell International makes a similar UHMWPE fiber, called Spectra®.
• Hand/Feel: Very slippery so is often used with modern sheaveless blocks and thimbles. Not good at holding knots but easily spliceable with a 12-strand eye splice. Must be covered with a heat-resistant jacket where it wraps around highly-loaded winches.
• Stretch: 0.70 % at 20% of breaking strength (after 50 cycles)
• Specific Gravity: 0.98 (floats)
