Polyester flat web lifting slings are typical for various applications requiring minimum stretch. They are similar in size and rating to nylon slings but are less flexible. They can be used for many different environments and can withstand most chemicals and other materials, although they are not suitable for acids and strong alkalis. These slings must be stored at temperatures below -40deg C.
A: When choosing polyester flat web slings, it is vital to consider the slings’ conditions to be exposed to acids. These slings are suitable for most environments where there is no need to use materials that have an acidic environment. For example, they can be used in environments with moderate acid levels. However, they are not suitable for temperatures that are too high or too low.
B: The two most common conditions where polyester web slings should be used are in areas where the material is highly contaminated. The material should not be exposed to any types of acids, but it should not be placed in areas exposed to concentrated sulfuric acid or alkaline. If the environment has a high temperature, it should be avoided. The best polyester flat web lifting slings have 3% stretch and are ideal for most lifting applications.
C: Despite these materials’ relatively high weight and strength, polyester web slings do not have the same amount of stretch. This means that the weight carried by a polyester web sling is less than one-tenth as much as its Nylon counterpart. Moreover, the material is more expensive and is better for the environment. And certain chemicals can affect the materials that polyester and Nylon are made of, so it is crucial to choose the right one.
D: The advantages of polyester flat web lifting slings are their low cost and excellent performance. They are strong, durable, spark-resistant, and non-conductive. Unlike Nylon, they do not rot. The material is not prone to abrasion. Its strength makes it an ideal choice for handling hazardous materials. Aside from being cost-effective, polyester flat web slings are durable and economical.
E: Another benefit of polyester flat web lifting slings is that they have a high level of stretch resistance. Unlike Nylon, polyester slings have meager heat resistance. Hence, they are suitable for handling loads with minimal stretch. They are lightweight and can be used in various conditions. In addition to their affordability, they are also safe and durable, so they are a popular choice.
