What effect does plasticizer have on the performance of pvc products?

Plasticizers, also known as plasticizers, refer to substances that can increase the plasticity of polymer compounds or polymer materials. The role of the plasticizer is mainly to reduce the hardness of PVC, reduce the processing temperature, increase the elongation, and relatively reduce the strength. That is to say, the mechanical changes of plasticizers to PVC are lower or reduce the desired performance, and the difference is nothing more than the degree of change.

FAQ

How do plasticizers affect the hardness of PVC?

Increasing plasticizer dosage lowers the Shore hardness of PVC, producing softer and more flexible end products. Hardness can be precisely tuned by selecting the right plasticizer type and concentration.

How do plasticizers affect PVC flexibility and elongation?

Plasticizers reduce the intermolecular forces between PVC polymer chains, allowing the chains to slide past each other more freely. This increases elongation at break and overall flexibility while lowering processing temperature.

How do plasticizers affect low-temperature performance?

Standard plasticizers can make PVC brittle in cold environments. Cold-resistant plasticizers such as DOS and DOA maintain flexibility at sub-zero temperatures, which is essential for cables, frozen food packaging and outdoor applications.
