Both nylon and polyester slings are suitable Polyester Flat Webbing Sling for fragile loads, but if you want to know which one is best for the most fragile loads, it is polyester. The chemical coating on the nylon webbing gives it a slightly rough texture.Polyester is also slightly more flexible than nylon. By being flexible, I'm not talking about stretching, but about the ability to tightly wrap the load and grab the maximum surface area.This is an important difference, especially when choosing between nylon headless slings and polyester headless slings.

It is also important to note the difference between flat mesh polyester sling and round polyester sling. Another key question to ask when choosing between nylon sling and polyester sling is, what are the environmental conditions? There is a reason ship porters and those in the marine environment prefer polyester slings. They absorb less water and are more resistant to UV rays. However, you also need to consider differences in chemical resistance. If you work near sulfuric acid, nitric acid, hydrochloric acid, or phosphoric acid, avoid using nylon slings.

Nylon is also not resistant to oxidizing bleaching agents, such as sodium hypochlorite, hydrogen peroxide, sodium percarbonate and calcium hypochlorite. On the other hand, the Achilles' heel of polyester is ether and alkali. Among other chemicals, this includes ether, dimethyl ether, sodium hydroxide, potassium hydroxide, calcium hydroxide, calcium carbonate and magnesium hydroxide.

In short, synthetic slings are a good choice because of their ability to handle fragile loads, lower cost, light weight and high strength. In the battle between polyester sling and nylon sling, the winner is the one that best meets your specific job requirements.Nylon slings have greater elasticity, but cannot be used near acids or bleaching agents. Polyester sling is softer and can better wrap the surface, but it cannot be used near ether or alkali.
