3 Strand Multi-filament Polypropylene is a light floating rope that is strong and easy to splice. Uses are anchoring lines, mooring lines fender lines Min Break Strength (kgs) 3290 Polypropylene Polypropylene (PP), also known as Polypropene, is a thermoplastic polymer used in a wide variety of applications. It is produced via chain-growth polymerization from the monomer propylene. Polypropylene has a melting point of 160 °C and the fibre floats. Various forms of Polypropylene yarns are used to produce ropes such as Split film, Yarn construction, multifilament, and monofilament each type produces a rope with different properties and uses.
