WR² is made of 100% HMPE fiber that is comprised of Dyneema® SK75. It’s the perfect wire rope replacement for lifelines and selected standing rigging.
Very little degradation from sunlihgt. Can be used outside over long term if inspected regularly.
HMPE has good resistance to most minerals, organics, acids, and weak alkalines. HMPE also has excellent resistance to bleaches and other oxidizing agents and to most solvents.
HMPE melts at 300F with progressive strength loss above 150F
Good resistance to the passage of electric current. However dirt, surface contaminants, water entrapment, and the like can significantly affect dielectric properties. Extreem caution should be exercised any time a rope is in the procimity of live circuits.
Recommended sheave diameter to rope diameter is 8:1
use the Brummel splice to splice the core to itself, whip the cover to the throat of the splice
