Wire & Cable Compounding: ATH Selection Guide for LSZH and HFFR Cable Systems
PF-1 Series — Ultra-Fine Precipitated ATH
The PF-1 Series is produced through a controlled chemical precipitation process and features a fine particle size distribution, high chemical purity, and high whiteness. PF-1S is a surface-treated version designed for improved filler–polymer compatibility in selected cable and elastomer formulations.
Parameter | PF-1 (Standard Grade) | PF-1S (Surface-Treated Grade) |
Manufacturing Process | Chemical Precipitation | Chemical Precipitation |
Median Particle Size (D50) | 1.6 – 2.0 μm | 1.6 – 2.0 μm |
Surface Treatment | None | Customized Silane coated |
Conductivity | ≤ 30 μS/cm | ≤ 40 μS/cm |
Whiteness (R457) | ≥ 98% | ≥ 98% |
Typical Applications | LSZH insulation, thin-wall wire compounds | Cable insulation, rubber cable compounds, elastomer systems |
PF-COP Series — Engineered Ground ATH
The PF-COP Series is manufactured through mechanical milling and air classification. Different particle size grades are available to support a range of cable compound formulations and processing requirements.
| Grade | Median Particle Size (D50) | Oil Absorption | Typical Applications |
| PF-COP3 | 2.0 – 4.0 μm | ≤ 35 ml/100g | Engineering plastics, specialty cable compounds |
| PF-COP5 | 4.0 – 6.0 μm | Controlled | Standard LSZH jackets, industrial compounds |
| PF-COP8 | 7.0 – 9.0 μm | Controlled | EPDM/EPR cable systems, industrial profiles |
| PF-COP11 | 10.0 – 12.0 μm | Controlled | FR-PVC compounds, bedding materials, adhesives |
Quick Grade Selection Matrix
Application | Recommended Grade | Selection Consideration |
LSZH / HFFR Insulation Compounds | PF-1 or PF-1S | Fine particle size and high purity |
Thin-Wall Automotive Wire | PF-1S | Surface-treated grade for enhanced compatibility |
Standard LSZH Bedding & Jackets | PF-COP5 or PF-COP8 | Balanced processing characteristics and cost |
Cost-Optimized High-Fill Formulations | PF-1 + PF-COP5 | Combination of fine and coarse ATH grades |
Flame-Retardant PVC Cable Compounds | PF-COP11 | Coarser particle size distribution |
Silicone Rubber Insulation Components | PF-1S or PF-COP3 | Suitable for silicone rubber and specialty elastomer formulations |
