Ultrex is a 12-strand single braid of High Modulus Polyethylene (HMPE) fiber from DSM Protective Materials and enhanced with Yale’s Maxijacket High Performance coating, which supplies superior abrasion resistance. Ultrex’s braid angles and twist level are designed to optimize break strength and keep stretch low.
HMPE is the most forgiving high-modulus fiber, giving better sheave-cycling capabilities than other high-tech fibers. Ultrex has zero water absorption and maintains its flexibility even in freezing conditions. As is the case for most Yale ropes, the strengths shown in the charts are for spliced ropes.
- Low elongation
- Zero water absorption
- Light weight allows rope to be set in by helicopter
- Superior abrasion resistance with Maxijacket HP coating
- Maintains flexibility even in freezing conditions
