High Silica Sewing Thread coated with PTFE
High Silica Sewing Thread coated with PTFE is
made of multi-ply 96% SiO2 silica fiber yarn treated with PTFE after high twist
compound. High silica sewing thread with PTFE features high tensile strength
and high abrasion resistance, good sewing property and high temperature
resistance.
Silica based materials provide burn-through
protection from molten metal and weld splatter.
Used at 2012°F / 1100°C continuously, used
at 2552°F / 1400°C instantly, molts above 3000°F / 1650℃.

Note: 1.
As this silica sewing thread is leached silica(leached silica have less tensile
strength), when it’s used in industrial high speed sewing machine require a
transmission to limit the velocity less than 30 punches per minute to
avoid to break the thread.
3. Roll weight around 500g/spool, 24rolls/ctn.
