The polyester cover provides abrasion resistance, while the Kevlar core provides the strength. Used in high temperature applications. Can be used outside over long term if inspected regularly. Good resistance to most chemicals.
Synthetic fiber has good resistance to passage of electrical current.
However, in rope form, dirt, surface contaminants, water entrapment and the like can significantly affect dielectric properties. Extreme caution should be exercised any time a rope is used in proximity to live circuits. No blanket working load recommendation can be made because it depends on the application and conditions of use, especially potential danger to personnel. It is recommended that the user establish working loads and safety factors based on professional and experienced assessments of risks. The working load is a guideline for the use of a rope in good condition for non-critical applications and should be reduced where life, limb, or valuable property are involved, or for exceptional service such as shock, sustained loading, severe vibration, etc.
