Tips on synthetic materials
Synthetic slings are made of nylon and
polyester to suit various applications.
When choosing a material, STREN-FLEX® recommends considering a material's resistance to specific chemicals, temperature, and stretch factor. STREN-FLEX® recommends
nylon web slings for most web sling applications, and polyester roundslings are
useful in applications requiring low stretch and acid resistant materials.
All standard STREN-FLEX® slings are sewn using nylon webbing unless polyester webbing
is specified by the consumer.
Nylon
Nylon is the most widely used general purpose synthetic web sling. Nylon is unaffected
by grease and oil, and the material has excellent chemical resistance to aldehydes,
ethers, and strong alkalies. However, nylon slings are not suitable for use with
acids and bleaching agent or at temperatures in excess of 194 degrees F (90 degrees
C). The stretch of a nylon sling at rated capacity is approximately 8-10%.

- Monster Edge® - Monster Edge® nylon slings contain energy absorbing fibers that increase
cut resistance and web protection. Monster Edge slings provide the increased abrasion
resistance needed for many industrial applications. Monster Edge has proven its
durability, and is considered the best product.

Polyester
Polyester web slings are used primarily in conditions where acid is present
or a minimum stretch is desired. Polyester is unaffected by common acids and hot
bleaching agents, but the material is unsuitable for use in conditions where concentrated
sulfuric acid and alkaline is present. Polyester is also unsuitable in locations
where temperatures exceed 194 degrees F (90 degrees C). Stretch of a polyester web
sling at rated capacity is approximately 3%.
