Thermal Stabilizer for PVC Magnesium Aluminum Carbonate Hydroxide CAS 12304-65-3 to Suppress HCl Degradation
Product Name: Hydrotalcite adsorbent / Magnesium Aluminum Carbonate adsorbent
CAS No.: 12304-65-3
Molecular Formula: [M(1-X)2+Mx3+y(OH)]x+(An-)x/n·mH2O
Product Introduction:
As an eco-friendly acid scavenger for PVC processing, this compound absorbs HCl generated during thermal degradation. Its layered structure delays dehydrochlorination, extending polymer lifespan while maintaining clarity in rigid/flexible PVC applications.
