1.52g/cm3 Soft PVC cable insulation compounds Flame Retardant PVC Cable Compounds
PVC has been used for cable insulation since 1932, originally as a replacement for rubber. Due to their relatively high dielectric strength, leading to corresponding induction losses and heating, soft PVC cable insulation compounds are only used at AC voltages of up to 10 kV. Most soft PVC cable mass applications are in this field. Formulations can be adjusted to customize the application temperature range, mechanical characteristics and flexibility of use, flammability and processing.
Here are two examples:
Cable PVC Compounds TDS

| 5 | Minimum Tensile strength after ageing for 7 days at 100 ±2 ºC | kgf/mm2 | 1.28 Min | BS EN 60811 | |
| 6 | Minimum Elongation after ageing for 7 days at 100 ±2 ºC | ≥% | 150 Min | BS EN 60811 | |
| 7 | Max. Loss of mass after ageing 7 days at 100℃ | ≤Mg/cm3 | 1.5 | BS EN 60811 | |
| 8 | Flame Retardant Grade | HB | |||
The main application fields of cable insulation mass produced with PVC cable compounding systems are power transmission up to the aforesaid 10 kV, domestic installations above all in private housing, and data transmission in general. The automobile industry almost exclusively uses soft PVC compounds.
