Product Description

Durak Duralon® is a high-tenacity Nylon 6,6 sewing thread produced with flame-retardant properties. The surface of the thread is treated with a flame-retardant chemical in compliance with standards using a chemical coating method. Even after 20 washes, it can maintain its flame-retardant performance according to NFPA 701. When removed from the flame source, it self-extinguishes by melting.
