Procurement Guide for Airtight Filling Yarn

(Disclaimer: Some of the information in this article is sourced from the internet. Please carefully identify and use it.)

Product Overview: The airtight filling rope is made of modified polypropylene (PP) as the substrate, which can isolate water vapor and gas penetration, ensuring long-term dryness inside the cable.

Key performance indicators (for reference only, not used as procurement standards)

• Airtightness: Gas leakage rate<1 × 10^-8Pa ·m³/s (GB/T 17713 standard).
• Pressure resistance: withstand 1.5 times the working pressure (≥ 0.6MPa) without deformation.
• Environmental friendliness: Passed RoHS and REACH environmental certifications.

Application scenarios

Suitable for sealing and filling natural gas pipeline cables, food processing plant cables, and medical equipment cables.

Procurement precautions

• Airtightness testing: A airtightness testing report is required.
• Customization requirements: Support customization of wire diameter according to cable diameter (φ 1mm-20mm).
• Cost analysis: Low prices may be due to secondary recycling materials. Avoid choosing low-priced products without testing reports.
