PTFE THREAD
PTFE coated fiberglass thread is made from continuous fiberglass filaments that are heat resistant, chemical resistant, and strong. The fiberglass is also coated with a PTFE / Teflon finish to improve sewability, and reduce friction.
PTFE coated fiberglass thread withstands operating temperatures to around 1022 F (550 C). But, the PTFE coating burns away at 620 F (320 C) and will propagate flame. Its continuous fiberglass filaments that are heat resistant, chemical resistant, and strong. It is Teflon coated for easy sewing. Based on PTFE / Teflon filament fiber, it can be processed into various kinds of high-performance mesh, fabric, sewing thread, dental floss, film and other result products
Features:

Applications:
PTFE Coated Fiberglass Thread is mostly used in dry filtration and insulation applications. The fiberglass has excellent thermal stability, and can withstand operating temperatures to around 1022 F (550 C). It is important to note the PTFE coating burns away at 620 F (320 C). This means the coating will propagate flame, but the fiberglass will have a higher resistance to flame. PTFE coated fiberglass thread is usually used for filter bags, insulation jackets, heat shields, spray shields, high temperature gaskets and seals, high heat composites, and welding blankets.
PTFE coated fiberglass thread is usually too thick for safety Apparel. Also, the fiberglass may irritate skin. For heat resistant safety apparel, Fire Retardant Sewing Thread is the better choice. It has a broader color selection, and wider variety of sizes. While PTFE coated fiberglass thread can withstand higher temperatures, it will melt when it reaches its temperature threshold. When it melts, it sticks to the skin. When Kevlar, Nomex or fire retardant thread reach their thresholds, they turn to ash and crumble without melting or sticking.
