SI9984 Ultra-low Dielectric Quartz Fiber Yarn

Ultra-low Dielectric Quartz Fibre Yarn Description

Ultra-low Dielectric Quartz Fibre Yarn is manufactured from quartz fibre (SiO₂) and exhibits an ultra-low dielectric constant. This material is characterised by its high-frequency insulation capability and stable performance in electrically sensitive environments. Its fine fibre structure facilitates minimal signal loss and reduced capacitance, making it suitable for applications where electrical isolation is critical. The yarn’s physical and chemical consistency supports predictable behaviour under variable thermal conditions.

Ultra-low Dielectric Quartz Fibre Yarn Applications

1.       Electronics
   - Used as an insulating layer in high-frequency circuit boards to reduce signal crosstalk by leveraging its low dielectric constant.
   - Applied as a dielectric barrier in miniaturised electronic components to enhance overall signal integrity by minimising parasitic capacitance.

2.       Industrial
   - Serves as a reinforcing insulation material in composite structures to improve electrical separation while maintaining mechanical stability.
   - Frequently used in sensor housings to ensure minimal electrical interference in environments requiring stable dielectric properties.

Ultra-low Dielectric Quartz Fibre Yarn Packing

Ultra-low Dielectric Quartz Fibre Yarn is packaged in moisture-resistant, anti-static bags which are then secured in rigid, cushioned containers. Storage conditions require a stable, dry environment to prevent contamination and degradation of the fibre properties. Custom packaging options, incorporating additional seals or protective liners, are available to address specific transportation and storage requirements.

Frequently Asked Questions
