"12-strand single braid construction. Each strand utilizes the lightweight properties of polyolefin wrapped in high tenacity polyester. The result is a firm, round, torque-free rope that has excellent abrasion and snag resistance. DaPro is ideally suited for lifting and handline applications."

The abrasion resistance and low UV degradation make it a good choice of rope for tree swings. It has specks of color in it and is easy on hands. This 1/2" rope is rated at 7000 lbs when new. It should be expected to last 5-10 years outside, although if conditions are moist or if subjected to constant & direct UV, the strength can be reduced further. No testing has been done to establish a baseline for how long rope can be left in trees year round.

Common Industry Applications other than for Tree/Rope Swings:
Hand Lines
Bull ropes
Adjustable slings
Tie downs
Heaving lines
Ship assist lines

• Breaking Strength, when new, is 7000 lbs.
• Working Loads: No blanket safe working load (SWL) recommendations can be made for any line because SWL's must be calculated based on application, conditions of use, and potential danger to personnel among other considerations. It is recommended that the end user establish working loads and safety factors based on best practices established by the end user's industry; by professional judgment and personal experience; and after thorough assessment of all risks. The SWL 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 is involved, or in cases of exceptional service such as shock loading, sustained loading, severe vibration, etc. The Cordage Institute specifies that the SWL of a rope shall be determined by dividing the Minimum Tensile Strength of the rope by a safety factor. The safety factor ranges from 5 to 12 for non-critical uses and is typically set at 15 for life lines.

Sunlight/UV:
Very little degradation from sunlight. Can be used outside over long term if inspected regularly.

Chemicals:
Polyester has good resistance to most chemicals, except 95% sulfuric acid and strong alkalines at boil. Polypropylene has excellent resistance to most acids and alkalines, except chlorosulphonic, concentrated sulfuric acids, and chlorinated hydrocarbons at 160°F. Additionally polypropylene withstands most diluted bleaching solutions.

Heat:
Polyester melts at 480°F with progressive strength loss above 300°F. Polypropylene melts at 330°F with progressive strength loss above 200°F.

Dielectrics:
Good resistance to the passage of electrical current. However, dirt, surface contaminants, water entrapment, and the like can significantly affect dielectric properties. Extreme caution should be exercised any time a rope is in the proximity of live circuits.

Sheaves:
Recommended sheave diameter to rope diameter is 8:1.
