Quartz Fiber

• Ultra pure, SiO2 content not less than 99.95%.

• High-temperature resistant.

• Ablation resistance.

• Low thermal conductivity.

• Anti-heating vibration.

• Low dielectric property.

• Excellent chemical stability.

Specification:

Properties:

• High temperature use(1050℃ long term, higher temperature possible in case of short term exposure)

• Resistance to thermal shocks

• Low thermal conductivity

• High electrical resistivity

• Low dielectric constant

• Good chemical resistance

Application:

• Thermal protection systems.

• Ablation materials used in aerospace and other fields.

• Filtration of hot acidic liquid and gases.

• Furnace closures and insulation.

• Asbestos replacement.

• High temperature insulation for semiconductor industry.

• Catalytic support for heavy duty vehicles catalytic converters.

• Raw material for quartz fiber felt.

Specification:

Quartz fiber twistless roving is assemblies of fused quartz continuous filaments combined into strands/ends, then assembled without intentional twist.

Application:

Weaving fabric (woven or stitched), Filament winding,  Pultrusion,  Unidirectional prepregging,   texturizing.

Quartz fiber yarn is assemblies of continuous high purity (SiO2 content ≥99.95%) quartz filaments (filament diameter 7-9um) gathered into strands(forming packaged), then processed with varying levels of twist and ply. Quartz fiber yarn had many superb properties: high purity, high temperature resistance, ablation resistance, low heat-conduction, anti-thermal shocks, excellent dielectrical property and chemical stability.

Specification:

Application:

Make fabrics for furnace lining in industrial applications and semicon.

High temperature seals.

High temperature cables.

Filtration at elevated temperature and/ or in strong corrosion environment.

Thermocouple insulation.

Thermal protection.

Insulation in automotive exhausts.

Radome.

Electromagnetic window.

Stealth material with structural performance.

Ablative materials.

Hollow quartz fiber yarn is same as quartz fiber yarn except its hollow filaments. With the hollow filaments, quartz fiber yarn gains much better properties in lower density, higher electrical conductivity, better wave permeability, more dielectrical property and heat insulation.

Specification

Quartz fiber sewing thread is made from high purity, extremely fine continuous filaments of pure fused quartz which is capable of exposure to 1070℃. Fiber composition is 99.95% SiO2 exclusive of binder. It has excellent abrasion performance and soft characteristic, widely used as high temperature filter material and sew up braided fabrics.
