Composition of Calcium/Zinc based Stabilizers

  • Calcium

This element contributes to the stabilizing effect by forming complexes that help mitigate the degradation of PVC under heat and other environmental conditions.

  • Zinc

Zinc acts synergistically with calcium to provide additional stabilization, especially against thermal and UV-induced degradation.

Benefits of Calcium-Zinc-based Stabilizers

  • Enhanced Heat Stability 

These stabilizers significantly improve the heat stability of materials, making them suitable for applications where exposure to elevated temperatures is common. This is crucial in ensuring the longevity and structural integrity of products like PVC pipes and construction materials.

  • Weather Resistance

The stabilizers enhance the weather resistance of materials, protecting them from the deteriorating effects of sunlight, rain, and other environmental factors. This is particularly beneficial in outdoor applications such as window profiles and PVC pipes.

  • Enhanced Safety in Flexible PVC Products

In applications like cables and wires, Calcium/Zinc-Based Stabilizers contribute to the flame resistance of the end products. This is essential in ensuring safety compliance, especially in industries where fire resistance is a critical factor.

  • Aesthetic Preservation

These stabilizers play a vital role in preserving the aesthetic qualities of materials, particularly in applications like vinyl flooring. They prevent degradation and ensure that the products retain a polished appearance, even in high-traffic areas.

  • Extended Product Lifespan

By preventing degradation and maintaining stability, they reduce the need for frequent replacements and offer sustainable stabilization to PVC products. 

Additionally, these stabilizers help create more environmentally friendly PVC goods by adhering to industry requirements on product safety and environmental effect. 

Uses and Applications of Calcium-Zinc based One Pack Stabilizer

  • PVC Pipes

These stabilizers find extensive use in the manufacturing of PVC pipes, ensuring they remain structurally sound and durable over time.

  • Window Profiles 

Calcium/Zinc-Based Stabilizers contribute to the longevity and performance of PVC window profiles, making them resistant to weathering effects.

  • Flexible PVC Products

In applications like cables and wires, these stabilizers maintain flexibility while also providing flame resistance, meeting safety standards.
