JY-7215 Cable Shielding Carbon Black for Conductive Cable Compounds
JY-7215 Cable Shielding Carbon Black for Conductive Cable Compounds
JY-7215 is a high-performance, specialty carbon black engineered specifically for electromagnetic interference (EMI) and radio-frequency interference (RFI) shielding in conductive cable compounds. Designed for demanding B2B industrial applications, it delivers consistent electrical conductivity, excellent dispersion stability, and superior processability in thermoplastic and thermoset cable jacketing and insulation formulations.
Key Features:
- Optimized particle size and structure for low percolation threshold in polymer matrices
- High surface area and tailored aggregate morphology for reliable shielding effectiveness (>60 dB at 1 GHz)
- Excellent thermal and oxidative stability — maintains performance during extrusion and long-term service
- Low volatile content and minimal ash residue — ensures compliance with RoHS and REACH
- Consistent batch-to-batch quality with tight control over DBP absorption, iodine number, and pH
Primary Applications:
- EMI/RFI-shielded data & telecom cables (e.g., USB-C, HDMI, Ethernet)
- Automotive wiring harnesses requiring ISO 11452-4 compliance
- Industrial automation and robotics cables with static-dissipative or conductive requirements
- Medical device interconnects requiring controlled surface resistivity (10⁴–10⁸ Ω/sq)
- Shielding layers in multi-layer cable constructions (e.g., inner semi-conductive shields, outer conductive jackets)
Technical Integration:
JY-7215 functions as a high-efficiency shielding carbon black filler and conductive cable additive, enabling formulators to achieve target volume resistivity (typically 10²–10⁵ Ω·cm) at lower loadings (15–25 wt%) vs. standard carbon blacks — reducing compound density and improving melt flow. Compatible with PE, PP, PVC, TPE, TPU, and crosslinkable EPR/EPDM systems.
Supplied in moisture-proof multi-wall paper bags (10 kg, 25 kg) or bulk FIBCs. Custom packaging and regulatory documentation (TDS, SDS, CoA, IEC 62321 test reports) available upon request.
