Trawl or Bridle Lines
Polyester – DurastatPolyester double braid has slightly higher strength as compared to nylon, but there the similarity ends. Opposite to nylon, polyester has the lowest stretch of any conventional synthetic fiber. With low stretch, double braid polyester is ideal for controlled lifting and pulling applications such as use with winches, capstans, chives, block and tackle. Other benefits of double braid polyester include, limited creep, and high abrasion resistance.
Superpro®Orion’s Sima extrusion process blends polypropylene and high modulus polyethylene resins to produce the co-polymer fiber used in making SuperPro® ropes. SuperPro® is 35% stronger and has many times the abrasion resistance of conventional polypropylene products, with low-elongation characteristics equivalent to pure polyester. Orion’s testing shows that SuperPro® significantly outperforms other “blended olefin” fibers that are extruded using processes other than Sima. SuperPro® co-polymer rope, available exclusively from Orion Ropeworks, offers the best performance-price value.
