Quartz Fiber Cotton Strips
Ultra-High Purity Quartz Fiber Cotton Strips for High-Temperature & Electrical Insulation
Quartz Fiber Cotton Strips are manufactured from ultra-high purity quartz fibers (SiO₂ ≥ 99.9%), processed into a soft, flexible cotton-like strip form.
These strips are designed for high-temperature insulation, electrical isolation, gap filling, and thermal sealing where material purity, thermal stability, and dielectric performance are essential.
Quartz fiber cotton strips are widely used in aerospace, defense, electronics, semiconductor, and high-temperature industrial systems, offering superior performance compared to conventional fiberglass or ceramic cotton products.
Key Performance Advantages
- Ultra-High Purity Quartz Fiber: ≥99.9% SiO₂
- Continuous Service Temperature: up to 1000–1050°C
- Excellent Electrical Insulation Properties
- Low Dielectric Constant & Low Dielectric Loss
- Very Low Thermal Expansion (CTE)
- Soft, Flexible & Conformable Structure
- Low Moisture Absorption
- Non-Conductive & Non-Magnetic
- Non-Asbestos & Environmentally Safe
Quartz fiber cotton strips maintain their insulation and dielectric performance even under thermal cycling and prolonged high-temperature exposure.
Product Characteristics
Quartz fiber cotton strips are produced by processing continuous quartz fibers into a loosely entangled, cotton-like structure, then formed into uniform strips. This structure allows:
- Easy installation in narrow gaps and complex shapes
- Uniform thermal insulation and electrical separation
- Effective sealing and cushioning in high-temperature zones
They can be used independently or as part of multi-layer insulation systems.
