Layerde Double Hydrotalcides (LDHs) is a kind of layered anionic functional inorganic material with adjustable chemical composition and unique structure and properties. When it is applied to PVC resins, the anionic layer can exchange with the free radical chlorine generated by the PVC degradation process, stabilizing the chlorine free radical between the laminates, thereby blocking further degradation reactions.
Our series of hydrotalcite has excellent thermal stability effect, is an excellent non-toxic heat stabilizer, using it as a heat stabilizer polymer material has outstanding thermal stability.
