Webbing Strength Characteristics
Polyester and nylon webbing are usually very strong.
Polyester webbing as a lower breaking point when compared to nylon webbing of the same type.
Polyester webbing can get wet and still be a very strong webbing.
However, nylon webbing is much weaker when wet. Nylon webbing will stretch when damp or wet.
Polypropylene webbing, on the other hand, is not that strong. However, polypropylene will float in water, and is great for use as a binder, such as batteries, because it resists battery acid very well.
