PVC Cable Compound Properties

PVC cable compounds are one of the most critical materials in the electricity and communications industry. Cable performance; Plasticizer selection is directly related to stabilizer structure, filler ratio and process parameters.

1. Mechanical Properties

• Flexibility and Impact Resistance

Cable compounds formulated with DOTP or DINP provide high flexibility even at low temperatures provides.

• Tensile and Tensile Strength

The combination of correct K-value PVC resin and Ca-Zn stabilizer provides high tensile strength.

2. Electrical Properties

• Insulation

PVC is naturally a good insulator; stabilizer and filler ratio can make or break this.

• Dielectric Strength

UL/CE of cable compounds critical for compliance with standards.

3. Thermal Properties

• TOTM/TINTM for high temperature resistance

• DOA for low temperature flexibility

• Thermal aging resistances are important

4. Flame Retardant (Optional)

Achieved by combinations of antimony trioxide + chlorinated paraffin + Ca-Zn.

Result

Cable performance, It depends on the quality of the additives used in the compound and the correct formulation. The right compound means the right application.
