nomex sewing thread
Yarn counts: 20s, 30s  etc
Properties:
1. High temperature resistant,
  70% strength of threads remains after being in 260 for 1000 hours
2.Excellent Flame resistant
 The limiting oxygen index (LOI) over 28%, wont burn, melt or drip, above 370, start to carbonize and decompose, no deleterious gas release.
3. Resistant to chemicals
  Resistant to most strong inorganic acid, excellent resistant to alkalis at room temperature.
4. Good textile properties
Low stiffness and high elongation, good mechanical property.
Mainly used in sewing the filter
