The wire and cable industry places stringent demands on the materials used for insulation and jacketing. Safety, flexibility, thermal resistance, and long-term durability are paramount. Traditionally, PVC has been a popular choice due to its excellent electrical insulation properties and cost-effectiveness. However, the stabilizers used in PVC formulations are critical for achieving the required performance and ensuring safety. Non-toxic Calcium Zinc (Ca-Zn) PVC stabilizers are increasingly becoming the preferred choice, offering significant advantages over older, hazardous alternatives. NINGBO INNO PHARMCHEM CO.,LTD. is a key supplier of these advanced, eco-friendly solutions.

The Critical Role of Stabilizers in Wire & Cable PVC

PVC compounds used in wires and cables must withstand thermal stress during processing (extrusion) and operation, as well as environmental factors like heat, UV light, and abrasion. Without effective stabilizers, the PVC can degrade, leading to:

  • Reduced dielectric strength (insulation failure)
  • Loss of flexibility, leading to cracking
  • Discoloration and embrittlement
  • Release of corrosive byproducts

The move towards non-toxic and environmentally friendly stabilizers is driven by both regulatory requirements and consumer demand for safer products.

Advantages of Calcium Zinc Stabilizers for Wire & Cable:

  • Non-Toxic and Environmentally Friendly: Ca-Zn stabilizers are free from lead, cadmium, and other hazardous heavy metals. This is especially important for wire and cable applications, where safety and compliance with regulations like RoHS and REACH are critical. As a trusted manufacturer, we ensure our products meet these standards.
  • Excellent Heat Stability: They provide robust protection against thermal degradation during the high-temperature extrusion process used to insulate wires and cables. This ensures consistent quality and prevents premature failure of the insulation.
  • Good Flexibility: Ca-Zn stabilizers can be formulated to maintain the flexibility of the PVC compound, which is essential for the installation and use of wires and cables.
  • Improved Electrical Properties: These stabilizers contribute to maintaining the excellent electrical insulation properties of PVC, ensuring reliable performance and preventing electrical hazards.
  • Good Weather and UV Resistance: For cables used in outdoor or exposed environments, the weatherability and UV resistance provided by Ca-Zn stabilizers help prevent degradation and maintain the integrity of the insulation.
  • Cost-Effectiveness: While offering superior safety and performance, Ca-Zn stabilizers are increasingly competitive in terms of cost, providing an excellent return on investment for manufacturers.
