Twisted Polypropylene Rope is one of the most widely used synthetic ropes. Here are some general characteristics:
- Designed to be tough
- Resistant to most acids, oils, grease, gasoline, diesel fuel, and most chemicals
- Lightweight and will float on the surface of water
- Little elasticity and will not stretch much before breaking
- Easy to splice together
- Rot-proof
- Not as strong as nylon
- Abrasion-resistant
- Very economical
- When tied into a knot, polypropylene will loosen if not tied tightly- the rope tends to return to its untied state
