Procurement Guide for Semi-conductive Non-woven Tape

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

Product Overview: Semi conductive non-woven fabric tape is made by uniformly embedding conductive particles into a polymer substrate, with low electrical resistivity (10³~10⁵Ω· cm), flexibility, and high temperature resistance (long-term temperature resistance of 150 ℃). It is specifically used for cable conductor shielding, binding, and metal layer shielding and isolation.

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

• Conductivity uniformity: Surface resistivity fluctuation ≤ 20% (ASTM D4496 standard).

Mechanical strength: Tensile strength ≥ 45N/cm, elongation at break ≤ 8%.

• Environmental friendliness: RoHS certified, free of polycyclic aromatic hydrocarbons (PAHs).

Application scenarios

Suitable for conductor winding of high-voltage cross-linked cables (such as YJV62), mining cables (MCPTJ), and rail transit cables.

Procurement precautions

• Conductive particle detection: SEM scanning electron microscopy images are required to confirm that the particle size is ≤ 10 μ m and evenly distributed.
• Supplier qualification: Priority should be given to manufacturers with IEC 60493-2 certification.
• Cost reference:Low prices may be for secondary recycled materials. Avoid choosing low-priced products without testing reports.

Frequently asked questions

Q: How to avoid the conductive layer from falling off during wrapping?

A: Select products with adhesive peel strength ≥ 4N/cm and control the wrapping temperature between 40-60 ℃.
