DURAK Poly-Strong PC CFR are cotton covered core threads to which a flame protective solution is added. This chemical flame retardant finishing method covers the surface of the threads according to international norms and quality standards. Even after 20 washes its properties are kept according to NFPA 701. They melt and self-extinguish once removed from the source of the flame. Even at very high speeds excellent seams are achieved. DURAK Poly-Strong PC CFR are suitable for many sectors because of high tensile strength, numerous colours and extensive ticket range.
