High Silica Wool
Ultra-High Purity Quartz Fiber Wool for Extreme Temperature & High-Reliability Insulation
Quartz Fiber Wool is a high-performance thermal insulation material manufactured from ultra-high purity quartz fibers (SiO₂ ≥ 99.9%) in a soft, lightweight, wool-like form.
It offers exceptional thermal resistance, very low thermal conductivity, and excellent dielectric properties, making it ideal for applications where temperature stability, electrical insulation, and material purity are critical.
Quartz fiber wool is widely used in aerospace, defense, electronics, semiconductor, and high-temperature industrial environments, where conventional glass or ceramic wool may not meet performance requirements.
Key Performance Advantages
- Ultra-High Purity Quartz Fiber: ≥99.9% SiO₂
- Continuous Service Temperature: 1000 – 1050°C
- Low Thermal Conductivity
- Excellent Electrical Insulation Properties
- Low Dielectric Constant & Low Dielectric Loss
- Extremely Low Thermal Expansion (CTE)
- Lightweight, Soft & Flexible Structure
- Non-Conductive & Non-Magnetic
- Low Moisture Absorption
- Non-Asbestos & Environmentally Safe
Quartz fiber wool maintains its insulating and dielectric performance even under thermal cycling and prolonged high-temperature exposure.
Material Characteristics
Quartz fiber wool is produced by mechanically processing continuous quartz fibers into a loose, entangled structure, resulting in a material that:
- Easily conforms to complex shapes
- Provides uniform insulation coverage
- Is suitable for filling, wrapping, or layering applications
It can be used as-is or further processed into mats, blankets, composite insulation systems, or resin-impregnated forms.
