Multifilament polypropylene is a general purpose rope that offers many advantages over traditional nylon or polyester such as being floatable strong economical and having good abrasion resistance. Multifilament polypropylene (MFP) is a relatively new development in the rope and cord industry with many advantages over traditional nylon or polyester. The main advantage of using MFP dock lines over traditional nylon or polyester is that they have relatively few if any stretch. Additionally it resists many chemicals rot and mildew making them perfect for use in marine environments. Additionally multi-stranded construction creates many small strands making the rope very flexible and it reduces the chances of tangles and knots. Additionally multi-stranded MFP ropes allow the rope to float in water reducing the chance of the rope slipping and falling to the bottom of the boat. Additionally it has high tensile strength which provides a strong anchor point if the rope is to be used as mooring rope limiting rope wear. Additionally multi-stranded MFP ropes are more resistant to wear and tear than their twisted or braided counterparts. Additionally multi-stranded MFP ropes are made with many small strands rather than hundreds or thousands like traditional nylon or polyester making them the perfect choice for abrasion-resistant rot-resistant and UV-resistant rope.
