A high proportion of modern webbing slings are made from synthetic fibres such as nylon, polyester and polypropylene. In this article we are focusing on polyester webbing slings and why it is such a suitable material for this purpose.
About polyester webbing slings
Polyester web slings are specially treated to be flexible, durable and hard-working and are suitable for a range of challenging and hazardous environments. During manufacture they are surface treated to seal out moisture, increase abrasion resistance and prevent particles (e.g. dirt, grime and grit) from penetrating inside the webbing, which would cause damage internally.
Examples of polyester slings in everyday use
Benefits of polyester webbing slings
Here is a list of benefits associated with the use of polyester in webbing slings:
Acid resistance – Polyester is resistant to acids and bleaching agents so is used in known acidic environments (N.B. Polyester is damaged by alkalis, where Nylon web slings should be used instead)
Colour coded – The web slings are colour coded to identify capacity limitations
Firm grip – Polyester webbing slings provide a firm grip/hold around objects being lifted
Lightweight – Polyester is lightweight making the webbing slips easier to carry around sites, wrap and store
Low cost – Polyester is available at relatively low cost compared to other materials (e.g. stainless steel wire)
Non-explosive – Polyester can safely be used in explosive atmospheres (e.g. mining), the material is both non-sparking and non-conductive
Quick drying – As a material Polyester is quick to dry due to its hydrophobic attributes, this is beneficial in certain environments
Resistance and durability – As well as acid, Polyester is resistant to many chemicals, mildew, moisture, oil and grease. In addition Polyester is resistant to UV degradation
Shape retention – Polyester is well known for retaining its shape, this can be a benefit compared to nylon web slings where space (e.g. headroom) is restricted and also reduces the risk of stretching and shrinkage
Softness – Polyester webbing is soft and is not prone to scratch or deface surfaces it makes contact with
Strength – Polyester is extremely strong and is capable of lifting extremely heavy loads. They are also shock absorbent, which makes it an ideal material for web slings
Versatile – Polyester web slings are available in a variety of applications which ensures versatility of use
Use the right webbing sling for the job
Although we have focused on Polyester in this article it’s always essential to use the right web sling for the job. Choose carefully the best material for the job in hand, e.g. choose Nylon in alkali environments.
