Quartzel® Sewing Thread

Made from fused silica filaments

Quartzel® fiber is a homogeneous, non-porous, continuous, amorphous, ultra-pure silica glass with a SiO2 content ≥ 99.95%. Quartzel® sewing threads are assemblies of 9µm filaments gathered into strands and then processed with twists and plies. Quartzel® sewing threads are offered either dry or coated with PTFE to facilitate its use.

 

Main properties:

Flexibility and sewability

Exellent lubrification of PTFE.

High mecanical strength

Filament tension RT= 6000 MPa.

Low thermal expension and resistance to thermal shock

CTE= 0.54 10-6 k-1.

Density

Density= 2.2
10% lighter than e-glass.

Resistant to acids

Good chemical inertness.
