1 Roll Pack of 1313 Aramid 403 Flame-Retardant Yarn, Temperature Resistant to 200℃ Under No Load, Temperature Resistant to 162℃ Under Load, 2000 Meters (Black)

Features

• Package Includes: you will receive 1 rolls of 403 aramid flame retardant thread in black, each 2000 meters long, the rolled-up dimensions are 4.45 x 2.76 inches, providing ample space for sewing critical areas such as seams and pockets on firefighter and arc-proof suits
• Flame-retardant Yarn: meta-aramid fibers have thermal stability, withstanding temperatures up to 200C under no load and 162C under load; They are also flame-retardant, stopping burning within seconds after the flame is extinguished, providing a crucial barrier for heat insulation and fire protection; Compared to traditional filament yarns, they are more resistant to strength loss caused by ultraviolet radiation; This aramid flame-retardant yarn is lint-free and has no joints
• Heat Resistant and Insulating: flame retardant thread offers strong electrical insulation, effectively preventing fire risks caused by short circuits and leakage, is ideal for high-temperature and high-arc environments; Insulation sewing meta aramids can also be applied for welding and metallurgical workwear, sewing high-temperature reflective strips or thermal insulation
• Safe and Durable: the flame retardant meta aramids thread itself is non-toxic and harmless, producing minimal smoke and no toxic when burned; The aramid fabric it is made of is soft and breathable, ensuring both safety and comfort, making it safe to use
• Wide Application: meta-aramid sewing thread offers excellent abrasion and tear resistance and is non-flammable, non-melting, and non-drip; Aramid 403 flame retardant thread applications include electrical insulation, protective clothing for firefighters and other first responders, race car drivers, and military personnel, as well as automotive heat shields and aerospace applications
