In the selection of materials for lifting and lashing equipment, two synthetic fibers, polyester and nylon, are often compared. Both materials offer high strength, wear resistance, and stable performance, making them widely used in industrial applications. However, when it comes to specific products such as flat webbing slings, round slings, and ratchet tie-down straps , polyester has become the industry’s standard choice. So, what exactly are the differences between polyester and nylon? And why are most lifting and cargo securing products based on polyester rather than nylon? What Is Polyester Fiber? Polyester fiber, commonly known as PET (Polyethylene Terephthalate) , is one of the most widely used synthetic fibers in industrial applications. Key Characteristics of Polyester: High tensile strength Low elongation under load Excellent dimensional stability Low moisture absorption Good resistance to UV exposure and acids Consistent performance in outdoor environments What Is...
