FR kevlar aramid sewing thread

Key Characteristics

Based on para-aramid 1414 (Kevlar® type), it is high-strength and lightweight with higher tensile strength than steel of the same weight, featuring low elongation, low creep and dimensional stability.

Permanent flame-retardant, self-extinguishing away from fire and non-dripping; it can withstand 260℃ for long-term use and higher temperatures for short periods, with low toxicity and non-combustibility during combustion.

Resistant to acids, alkalis, organic solvents, mildew, abrasion and cutting, suitable for harsh working conditions and long-term use.

Insulating and non-magnetic, applicable to special environments and electromagnetic compatibility requirements.

Available in filament twisted or staple fiber spun types; anti-abrasion/anti-fraying coating is optional for easy machine and hand sewing.

Common colors: natural golden yellow, solution-dyed black; customizable on demand.

Typical Applications

Seaming and reinforcement of firefighting suits, welding suits, arc protective clothing and metallurgical high-temperature workwear.

Sewing and reinforcement of military and police tactical uniforms, bulletproof vests, helmet liners and tactical vests.

Splicing and edge finishing of high-temperature filter bags, fire curtains, flame-retardant tents and fire blankets.

Sewing, prepreg and edge reinforcement of composite materials (e.g., aramid fabric, carbon fiber fabric) and epoxy/phenolic resin systems.

Seaming and fixing of industrial belts, high-temperature conveyor belts and fireproof seals.

Sewing of high-temperature area threads and rigging in aerospace, shipbuilding and offshore engineering.
