In the wire and cable industry, the insulation and jacketing materials must meet stringent performance and safety standards. Polyvinyl Chloride (PVC) is a widely used polymer for these applications due to its excellent electrical insulation properties, flame retardancy, and cost-effectiveness. However, like all polymers, PVC requires stabilization to withstand the heat and mechanical stresses encountered during processing and in end-use applications. Calcium Zinc (Ca/Zn) stabilizers have emerged as the preferred choice, offering enhanced safety and performance benefits over traditional lead-based systems. NINGBO INNO PHARMCHEM CO.,LTD. is a leading supplier of advanced Ca/Zn stabilizers, vital for the production of high-quality PVC wire and cable compounds.

The Critical Role of Stabilization in PVC Wire & Cable

PVC insulation and jacketing are subjected to significant heat during extrusion and processing. Furthermore, the finished cables operate under various temperature conditions and can be exposed to electrical stresses. Without adequate stabilization, PVC can degrade through:

  • Thermal Degradation: Leading to reduced electrical insulation properties, embrittlement, and potential safety hazards.
  • Dehydrochlorination: Releasing corrosive HCl gas, which can damage conductors and other components.
  • Color Change: Causing discoloration, which can be an indicator of underlying degradation and affect product acceptance.

Effective stabilizers are crucial for protecting the PVC material, ensuring its longevity, electrical integrity, and safety compliance.

Why Choose Calcium Zinc Stabilizers for Wire & Cable?

Calcium Zinc stabilizers offer several advantages that make them ideal for the demanding requirements of the wire and cable sector:

  • Excellent Thermal Stability: Our Ca/Zn stabilizers provide robust protection against degradation during high-temperature extrusion processes, ensuring smooth processing and consistent cable quality. This is crucial for manufacturers who want to buy reliable performance.
  • Improved Electrical Properties: By preventing degradation, Ca/Zn stabilizers help maintain the excellent dielectric strength and electrical resistance of PVC, which are critical for cable performance and safety.
  • Environmental and Health Safety: As lead-free and non-toxic alternatives, Ca/Zn stabilizers meet global safety standards (like RoHS and REACH), making them ideal for applications where human and environmental safety are paramount.
  • Flame Retardancy Enhancement: While PVC is inherently flame retardant, Ca/Zn stabilizers can synergize with other flame retardant additives to further enhance the fire performance of cable insulation.
  • Good Processing Lubricity: Many Ca/Zn formulations contribute to improved melt flow and reduced friction, facilitating higher extrusion speeds and better surface finish on the cable.
