SI9985 Ultra-low Dielectric Quartz Fiber Fabric

Ultra-low Dielectric Quartz Fibre Fabric Description

Ultra-low Dielectric Quartz Fibre Fabric is produced from high-purity SiO2 using a controlled fibre drawing and sintering process. The material’s microstructure is optimised to deliver a low dielectric constant and chemical inertness, making it suitable for electrical insulation in high-temperature environments. Its consistent fibre diameter and network structure ensure uniform performance critical for advanced ceramic applications in various industrial settings.

Ultra-low Dielectric Quartz Fibre Fabric Applications

Electronics
- Used as an insulating layer in high-frequency circuit boards to mitigate signal loss by leveraging its low dielectric constant.
- Applied as RF shielding in communication devices to reduce electromagnetic interference through its chemical inertness.

Industrial
- Serves as insulation in high-temperature furnace linings to maintain thermal stability by utilising its ceramic properties.
- Frequently used in sensor housings to prevent electrical conduction and ensure accurate measurements due to its ultra-low dielectric nature.

Ultra-low Dielectric Quartz Fibre Fabric Packing

The fabric is packaged in anti-static, moisture-resistant bags with cushioning inserts to prevent mechanical damage and contamination during transit. It is stored under controlled temperature and low-humidity conditions to preserve its properties. Additional packaging options, including vacuum-sealed pouches or reinforced containers, are available to meet specific handling and storage requirements.

Frequently Asked Questions

Q1: What processing controls are implemented to maintain the fabric’s low dielectric properties?
A1: SAM utilises scanning electron microscopy and spectroscopic analysis during fibre drawing and sintering to monitor microstructural uniformity. This controlled process reduces defects and maintains the targeted ultra-low dielectric performance.

Q2: How does fibre orientation affect the insulating performance of the fabric?
A2: Controlled fibre orientation minimises dielectric anisotropy, ensuring a homogeneous insulating barrier. This uniformity enhances performance in electronic components where consistent dielectric behaviour is critical.

Q3: Is it possible to customise the fabric for specific thickness requirements?
A3: Yes, customisation in thickness and fibre density is achievable by adjusting the fibre drawing and sintering parameters, allowing optimisation for various device integrations and operational conditions.
