Magnesium Aluminosilicate Adsorbent (CAS 71205-22-6) is crucial in polyether polyol production:
Polyether polyol raw materials often have impurities. Metal ions like iron and copper can trigger side - reactions if not removed, while acidic substances can degrade polyether chains. The adsorbent, with its porous structure, quickly adsorbs these metal ions and neutralizes acidic impurities, safeguarding the polyether polyol's molecular structure.
Color forming contaminants from raw materials or reactions are also adsorbed. This ensures the final product is clear and color less, ideal for high grade polyurethane products.
During polymerization, its excellent compatibility with the reaction system is a major advantage. It promotes a more uniform reaction, enabling better control of the reaction rate and molecular weight distribution. In short, this adsorbent is an essential additive for producing high - quality polyether polyols for the polyurethane industry.
