Phillystran aramid fiber ropes jacketed with abrasion-resistant, moisture-blocking extruded polymers are made to order for most shipboard applications. Phillystran ropes provide the strength and low-stretch characteristics of steel with the light-weight, non-corrosive, and dielectric properties of fiber ropes.
The U.S. Navy has approved Phillystran for use in lifelines and boat davit preventer stays. Some of the advantages of replacing steel cables for these applications are:
- Inter-modulation interference (IMI) is eliminated.
- Electromagnetic interference (EMI) is eliminated.
- Received and transmitted signal patterns are improved.
- Expensive maintenance such as painting, greasing, and de-icing is eliminated.
- Useful life is dramatically increased when corrosion due to sea water and stack gases is eliminated.
- Safety concerns due to metal "fish hook" injuries and corrosion-weakened steel wire ropes are eliminated.
Applications where electrically transparent, corrosion-resistant Phillystran is the best choice are:
- Mast and antenna stays.
- Jackstaff and canopy-awning lines.
- Boat gripes, preventer stays, and spanwires.
- Mooring lines.
- Tow lines and winch lines.
- Lashing ropes and rigging lines.

CAUTION: Break Strength: The breaking strength of a rope is the load at which a new rope will break when tested under laboratory conditions. Break strength should not be mistaken for safe working load. Safe Working Load: Because of the wide range of rope use, rope condition and the degree of risk of life or property, it is not possible to make a blanket recommendation for safe working load. It is ultimately dependent on the rope user to determine what percentage of break strength is their own safe working load. Wear: Ropes wear out with use; the more severe the usage, the greater the wear. It is often not possible to detect wear on a rope by visible signs alone. Therefore, it is recommended that the rope user determine a retirement criteria for ropes in their application. For assistance in developing safe working load and retirement criteria for each application please call or write Phillystran, Inc.
