Quartzel® Yarns

Made from fused silica filaments

Quartzel® yarns are assemblies of 9 or 14 microns continuous fused silica filaments assembled together and twisted. They are essentially used for their combined low dielectric properties, high mechanical strength and high thermal resistance.
 
 

Main properties

Free of impurities

99.95% silica content.

High mecanical strength

Filament tensile strength = 6000 MPa.

Low thermal expension and resistance to thermal shock

CTE= 0.54 10-6 k-1.

Ablative material

Above 1600°C and extreme heat flow.

Density

Density= 2.2
10% lighter than e-glass.

High elongation

Maximum elongation  ε= 7.7%.

Low shrinkage at HT

Shrinkage after exposure of 1000h at 1000°C < 1.5%.

Available sizings & packaging

Bobine H3

Available sizings : 

  • QS1318 and QS13-QPC1 are multipurpose high performance direct sizings, recommended for most textile processes and composite applications. They can be used with thermoset resins and among others : Phenolic, Epoxy, BMI, etc..
  • QSCY1 sizing is designed specifically for optimized compatibility with cyanate ester resin systems.

*Sizing is the chemical agent which aims at protecting the yarns in textile processes as well as providing chemical compatibility with resin matrix in composites.

Type of packaging: 

All Quartzel yarns are packed onto H3 bobbins. See the graph beside.
