Product Description
Flame retardant thread is a high-performance thread known for its exceptional strength, heat resistance, and flame-retardant properties. Made from aramid fibers, it resists abrasion, chemicals, and shrinkage. Significantly stronger than nylon or polyester, it remains stable in high-temperature environments. It is ideal for protective clothing, military gear, aerospace composites and industrial safety products ensuring reliability in demanding applications.
DERUSEN sewing thread have been certified with the OEKO-TEX® STANDARD 100 label , ensuring they are free from harmful chemicals and safe for sensitive skin. We are committed to providing you with high-quality, safe, and eco-friendly products.
Product Introduction
Flame retardant thread is a high-performance specialty thread crafted from aramid fibers (Aramid 1414/1313) with short-fiber, continuous filament, or composite variants. It integrates ultra-high strength, wide temperature adaptability, and flame retardancy, ideal for high-safety sewing in protective gear, industrial applications, and specialty products.
Product Highlights
Ultra-high strength (5-6x that of high-grade steel, ≥20.0 CN/dtex for Aramid 1414)
Wide temperature resistance (-196°C to 204°C long-term, withstands up to 585°C briefly)
Inherently flame-retardant (LOI ≥28, self-extinguishing, no melting)
Excellent chemical resistance (resists most acids/alkalis, stable after 50 washes)
Abrasion, cut, and puncture resistant
Lightweight (1/5 density of steel) and electrically insulating
Radiation-resistant (certain grades) with long service life
Application Fields
Protective gear (firefighter suits, bomb disposal suits, industrial high-temperature clothing)
Engineering materials (sewing high-temperature/tear-resistant fabrics, sealing materials)
Daily & specialty products (heat-resistant kitchen gloves, sports equipment, thermal insulation products)
