polypropylene line are very versatile and economical synthetic ropes that are known for their unique qualities like floatability, resistance to mildew, durability, color variety, and easy splicing. They are available in a wide range of colors, thicknesses and constructions, making them popular for use in cynology (because of their ability to float on the surface of water), leashes for dogs and horse leads, climbing nets and yachting.
The two most common braid poly rope options are solid and diamond braid designs. Solid braids are created by intertwining strands in a lock stitch pattern. Some solid braid ropes have a core, while others do not.

Diamond braid rope is made by alternating sets of 2 strands over and under each other. The result is a “maypole” type of braid that is lightweight and very easy to handle. This rope may also be used with or without a core, which is a personal choice that should be based on the intended application.
Both styles of polypropylene rope have excellent chemical resistance, which means they will do well in various outdoor environments. They are resistant to acids and alkalis, and hold up against petroleum-based products, solvents and bleaches. They also have low creep under a load and resist elongation very well. These properties make them very useful in marine applications, including buoy moorings, fishing lines and anchor lines, and even for designingating swimming lanes at golf courses or parks.
