Our braided nylon elastic meets the FMVSS 302 standard which specifies burn resistance requirements for materials used in the occupant compartments of motor vehicles. This would include things like seat covers, headliners and instrument panel padding. Of all our flat elastic material, nylon elastic is the strongest. Nylon elastic is ideal for most marine and outdoor applications as it is machine washable, does not float and has longer life span than other fibers. Nylon is one of the more expensive fibers and is a very high quality.
