Our high temperature fireproof sewing thread is a mainstream industrial stitching material specially developed for high heat and flame exposure working conditions. Made from premium alkali-free glass fiber raw material, this fiberglass sewing thread abandons the shortcoming of traditional cotton, polyester and nylon threads which melt and burn easily under high temperature. As a reliable fireproof sewing thread, it has stable physical and chemical performance and is favored by industrial buyers from all over the world.

This fiberglass sewing thread features excellent inherent flame retardant property. It will not sustain combustion when touching open fire, and no toxic smoke or harmful chemical gas will be released during high-temperature baking, complying with international general fire protection standards. As a professional high temperature resistant sewing thread, it can continuously bear 550°C high temperature, and will not shrink, harden or crack after long-time operation in hot environment.

The fireproof sewing thread has balanced tensile strength and smooth sewing performance. It can be used for manual sewing and all types of industrial automatic sewing machines, with less thread breakage and neat stitching lines. Besides, this fiberglass sewing thread has strong resistance against acid, alkali, grease and moisture erosion, and will not age quickly even in damp and dusty factory workshops.

We support optional PTFE surface coating treatment for this high temperature fireproof sewing thread. After coating, the thread gains extra waterproof, anti-sticking and wear-resistant functions, suitable for more harsh production scenes such as boiler heat preservation, high-temperature pipeline wrapping and chemical plant thermal sealing. Multiple thread diameters are available, standard white color is in stock, and customized specifications can be arranged according to buyer’s production requirements.

Wide application scenarios of this fiberglass sewing thread cover fire blanket sewing, fireproof curtain processing, high-temperature protective clothing stitching, thermal insulation cloth making, high-temperature filter bag production, boiler insulation sleeve and building fireproof accessories. This fireproof sewing thread serves many industries including fire safety, electric power, metallurgy, chemical industry, construction and new energy.

All high temperature resistant sewing thread is produced with standardized production procedures, with uniform thickness and consistent batch quality. Compared with ordinary stitching threads on the market, our fiberglass fireproof sewing thread has longer service life and lower replacement cost. It effectively improves the durability and safety of finished fireproof and heat insulation products, bringing stable cost control benefits for industrial manufacturers.
