BSTFLEX Silica Fiber Sewing Thread

Silica Fiber Sewing Thread is made of multi-ply 96% pure SiO2 silica fiber yarn treated with PTFE after high twist compound. It features high tensile strength, good sewing property and high temperature resistance.

Silica yarn is a necessary fitting material and used to sew filter bags,fire blanket on industrial high-speed sewing machine, also used to sew weak alkali-resistant weave and used in high temperature cable braiding.

It can be used below 1000℃ for a long period of time, with high tensile strength. It will fulfill the need of sewing filter bags used in carbon black/metallurgy/cement industries.

Continuous working temp.: 1100c degree
Instant working temp: 1400c degree

Silica Fiber Sewing Thread Application:
--Used for sealing and insulating products
--Sewing safety clothing, gloves, welding and fire blankets
