In recent years, with increasingly stringent global environmental regulations and the upgrading of downstream industries, the PVC products industry is rapidly developing towards a safer and more environmentally friendly direction. As a key additive in PVC processing, the performance and environmental attributes of heat stabilizers directly affect the application scope and market competitiveness of the final product.

PVC products are diverse, ranging from pipes and profiles to films and cables, each with different requirements for heat stabilizers. Choosing the right stabilizer system for different processing techniques and end-use environments is crucial to product performance and cost.

In PVC processing, heat stabilizers are the "guardians" ensuring basic processing safety, while modifiers such as CPE (chlorinated polyethylene) and ACR (acrylate processing aids) are the "enablers" improving the final product performance. A scientific combination of these three can achieve a synergistic effect of "1+1+1>3".
