PVC compound stabilisers are widely used in the production process of PVC products, such as pipes, film materials, cables, flooring, window frames and other fields. By adding PVC compound stabilisers, the service life and thermal stability of PVC products can be improved, so as to meet the needs of different application fields. At the same time, the reasonable selection and use of PVC compound stabiliser can also reduce production costs, improve production efficiency, is an indispensable and important auxiliary agent in the production process of PVC products.

1. Thermal stability:
Neutralise or passivate metal ions and other harmful impurities that play a catalytic role in degradation, prevent PVC from decomposing and degrading at high temperature, and maintain its thermal stability.
2. Improvement of processing performance:
No need for secondary grinding, saving consumables, and at the same time, improve the processing performance of PVC, such as increasing the melt fluidity, reducing the viscosity of the melt and so on.
3. Light stability:
Prevent PVC from aging under ultraviolet irradiation, improve aging resistance and inhibit oxidation of products.
4. Oxidation stability:
Prevent PVC from degradation by oxidation, prolong the service life of products.
Reduces the sliding ability between the interfaces. Therefore, the Mortar has strong bonding strength.
Thermal Stability:
Lead stabilizers prevent the degradation of PVC at high temperatures during processing.
They help maintain the material’s properties and prevent discoloration.
UV Resistance:
Lead stabilizers provide protection against UV radiation, which can cause PVC to become brittle and discolored over time.
Mechanical Properties:
They help maintain the mechanical strength and flexibility of PVC products.
Lead stabilizers improve the impact resistance and durability of PVC.
