Boost Sewing Performance with Steel-Reinforced Fiberglass Sewing Thread​

Unleash Superior Strength & Heat Resistance​

Experience the ultimate sewing solution with our advanced steel-reinforced fiberglass sewing thread, engineered to excel in the most demanding environments. Combining a high-tensile steel core with a durable fiberglass exterior, this thread delivers exceptional heat resistance (200°C to 1000°C), making it ideal for high-temperature applications such as industrial textiles, protective gear, and sealing components. Its unique structure ensures smooth, uninterrupted sewing without fraying or breakage, even on high-speed machines.

Key Features & Benefits​

Extreme Durability: The steel core provides unmatched tensile strength, while the fiberglass sheath offers flexibility and abrasion resistance. Say goodbye to frequent thread breaks!

Fireproof & Chemical-Resistant: With a A-level non-flammable certification​ (GB8624-2006/DIN4102 A1), this thread withstands flames, corrosion, and aging. It remains stable in harsh conditions, from chemical exposure to outdoor weathering.

Effortless Sewing: The smooth PTFE-coated surface reduces friction, preventing unraveling and ensuring clean, precise stitches every time. Perfect for fabrics like rubber, silicone, or reinforced composites.

Wide Applications: Ideal for producing fire blankets, protective curtains, insulation sleeves, and industrial seals. Also used in electrical insulation and high-temperature conveyor systems.
