Polyester Vs. Nylon Slings: Which One Is Perfect for Your Job?

Rigging Slings

You might be wondering if a polyester sling or nylon sling is the better option for your project. This is a common question, and the answer really depends on what job you need to get done. There are some differences in using these rigging slings.

Advantages of Slings

Synthetic slings are attractive to many because of the lower cost. If you want to know which is cheaper, the prices are about the same for each. Synthetic slings are often lighter, which makes them easier to handle and transport. Nylon is a little heavier than polyester, but the difference is often not significant.

Nylon can have stronger fibers, but polyester can be just as strong if it has more threading. Each type can often handle a lot of weight. Choose a sling that has a rating for the load you need to lift.

Physical Differences

Often, nylon rigging slings have more stretch to them. Nylon slings can have more stretch, but this does not make them weaker. In fact, you might want to have less stretch because of the over height lifting room and the possibility for a snapback.

If there are height limits, you may decide to go with polyester. But if the load could bounce a lot, you might go with nylon. Its extra stretch might reduce the chances of the strap snapping at others or you.

Polyester is often more flexible and softer. Both polyester and nylon slings are good options if you have a delicate load. But polyester often does not have a coarse texture like nylon. Plus, polyester is often more flexible. It has the ability to wrap around your load tightly, gripping more surface area.

Environmental Differences

Consider the environmental differences when you are looking for lifting and rigging equipment. Where will you be using it? For example, nylon slings often can’t withstand hydrochloric, phosphoric, sulfuric, or nitric acids. Nylon slings might also not do well with hydrogen peroxide, calcium hypochlorite, sodium hypochlorite, or sodium percarbonate.

Polyester chain slings might have trouble with alkalis or ethers. It might not handle calcium carbonate, magnesium hydroxide, sodium hydroxide, diethyl ether, calcium hydroxide, potassium hydroxide, or dimethyl ether. It is a good idea to keep these chemicals away from your polyester slings to prevent damage to them.
