PVC Cable Compound Specifications

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

1. Mechanical Properties

• Flexibility and Impact Resistance

Cable compounds formulated with DOTP or DINP, 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.
