SP-12 is a 12-strand blended rope comprised of Ultra High Molecular Weight Polyethylene (UHMWPE) fiber and polyester. This rope is designed to take advantage of the high strength and low elongation properties of UHMWPE fibers while providing a slightly lower price point than 100% UHMWPE ropes.
The primary market opportunity is for long length conductor pulling machinery. This rope can also be used in any application where 100% UHMWPE does not fit the need and 100% polyester is limited in selection as well. The rope is available in any of our Maxijacket HP colors which will be supplied as a standard coating. This product is identified by the addition of blue polyester fiber in the strand bundle of yarn.

* Knots and abrupt bends significantly reduce the strength of all ropes and lower the maximum working load.
** Working load is based on static or moderately dynamic lifting/pulling operations. Instantaneous changes in load, up or down, in excess of 10% of the rope’s rated working load constitute hazardous shock load and would void the normal working-load recommendation. Consult Yale Cordage for guidelines for working loads and the safe use of rope.
Green working 292 ft. lbs./lb.
Red ultimate 5,851 ft. lbs./lb.
Specific Gravity: 1.12
Dielectric Strength: The maximum allowable leakage for clean, dry SP-12 is 100 micro-amperes when tested at 100kV per Yale Method 712-1701 Rev 1 “Routine Production Test.”Absorbed and entrained moisture or impurities will increase rope’s conductivity dramatically.
