Product Description

DURAK Poly-Strong PP CFR® is produced by adding flame-retardant properties to 100% polyester-wrapped polyester sewing threads. Through a chemical coating process, the thread surface is treated with a flame-retardant chemical that meets the standards. Even after 20 washes, it retains its flame-retardant feature in accordance with the NFPA 701 standard. When removed from the flame source, it self-extinguishes by melting. It is a high-performance sewing thread with high resistance to abrasion in high-speed sewing. With high strength, bright colors, a wide range of thickness options, and superior performance, it is used in a variety of applications.
