Polypropylene braided rope is a type of synthetic rope made from a thermoplastic polymer called polypropylene. Unlike monofilament rope, it is made from multiple strands of polypropylene fibers that are braided or twisted together.
 
One of the main advantages of polypropylene braided rope is its high strength-to-weight ratio, which means that it can support heavy loads while still being relatively lightweight. The braided construction of the rope also makes it more resistant to repeated bending and flexing.
 
Polypropylene braided rope is also somewhat buoyant, which makes it a good choice for marine applications such as mooring lines and dock lines. It is also relatively inexpensive compared to other types of synthetic ropes, which makes it a cost-effective option for many applications.
