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:
Magnesium aluminum carbonate adsorbent offers great industrial application potential in transparent PVC stabilization systems. With remarkable adsorption capabilities, it can effectively capture harmful substances like HCl generated during PVC processing. This not only stabilizes the PVC but also maintains the transparency of the final product. By adsorbing impurities, it prevents discoloration and degradation, ensuring high quality, long lasting transparent PVC products. Ideal for industries demanding both optical clarity and thermal stability in PVC materials.

Application of Magnesium Aluminum Carbonate in PVC stabilization system:
Magnesium aluminum carbonate adsorbent is essential in PVC stabilization systems, especially for transparent PVC products. When PVC is processed, heat causes it to decompose and release hydrogen chloride (HCl) gas, which can trigger further degradation.
Thanks to its unique porous structure and chemical properties, the adsorbent has a strong affinity for HCl. It adsorbs HCl through both physical and chemical means. Physically, the large surface area pores allow HCl to adhere, while chemically, its components react with HCl to form stable compounds, removing HCl from the PVC matrix.
This HCl removal is crucial. Without it, HCl would catalyze PVC degradation, breaking molecular chains, causing discoloration, and weakening mechanical properties. By eliminating HCl, our adsorbent stabilizes the PVC structure.
In transparent PVC, impurities and degradation by - products reduce transparency. Our adsorbent prevents degradation-induced impurities and adsorbs existing contaminants, ensuring high quality, clear PVC products. Whether for films or sheets, it contributes to long-term stability.
