Teflon finish for dry filtration. Withstand 1000F temperatures
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, a.k.a Teflon (tm) finish to improve sewability, and reduce friction. It 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 greater heat resistance.
