What are the advantages and disadvantages of different materials of marine ropes?

In marine applications, there are five main types of fiber ropes, polypropylene, polyester, nylon, polymer, and aramid. Each has some good advantages, but also some disadvantages.

Rope often combines different materials to produce high-quality ropes according to customer needs, and maximizes the advantages of each material to meet customer needs. Marineusedgood.com give some detailed information for four main kinds of used material for ropes, which is highly and widly used in marine related area.

Polypropylene Rope:

　　 Advantages: 1. Floating water 2. Low price 3. Not sensitive to chemical attack 4. Strong and wear-resistant 5. No water absorption 6. No strong loss in water

　　 Disadvantages: 1. Poor UV resistance 2. Low strength 3. Low melting point 4. Low stretchability (not as good as nylon) 5. Hand feeling

　　 Uses: 1. Small boat main mast control rope 2. Rescue rope 3. Towing rope 4. Rope used on skis

Nylon Rope:

　　 Advantages: 1. Good UV resistance 2. Shock absorption (good stretch) 3. Good chemical resistance 4. Moderate price

　　 Disadvantages: 1. Too elastic 2. Performance weakens after being wet

　　 Uses: 1. Anchor line 2. Towing line 3. Mooring line 4. Safety line

Polymer Rope:

　　 Advantages: 1. High strength 2. Not wet with water 3. Good chemical resistance 4. Good abrasion resistance 5. Good UV resistance 6. Light and floating 7. Good resistance to flexural fatigue

　　 Disadvantages: 1. Too slippery 2. Low melting point 3. Easy to deform under continuous load 4. High price

　　 Uses: 1. High-performance rope used on yachts 2. Replace steel rope

Aramid Rope:

　　 Advantages: 1. High strength 2. Low stretchability 3. Not easy to deform 4. Fire resistance 5. Good chemical resistance 6. Cut resistance 7. Insulation

　　 Disadvantages: 1. Sensitive to ultraviolet rays 2. Sensitive to impact 3. Sensitive to chlorine 4. Poor flexural fatigue resistance 5. The strength becomes lower after knotting 6. The price is high

　　Usage: 1 winch rope 2 replace steel wire rope where weight is required 3 use on large ships without insulated cables
