PTFE sewing thread, also known as teflon sewing thread, is a high-performance specialty industrial sewing thread and an ideal choice for sewing high-end filter bags in baghouse dust collection systems.
Made from premium polytetrafluoroethylene (PTFE) material, this thread offers outstanding resistance to both high and low temperatures, allowing continuous operation within a temperature range of -180°C to 260°C. It also features excellent chemical resistance, aging resistance, and an extremely low coefficient of friction, effectively reducing wear at the seams and extending the service life of filter bags.
With superior heat resistance, corrosion resistance, and dimensional stability, PTFE Sewing Thread is widely used in high-temperature filtration applications, including cement, steel, waste incineration, power generation, and chemical industries. It is an essential auxiliary material for manufacturing high-performance industrial dust filter bags.
