China Chemical Auxiliary & Catalyst - Page 10

The DMC catalyst is double metal cyanide (DMC) catalyst. Compared with similar polyols made using basic(e. G., KOH)catalysts, polyether polyols made from the catalyst have low unsaturations, narrow molecular weight distributions, can have high molecular weight, and are useful in making a variety of polyurethane products.

DMC catalyst is highly active in epoxide polymerization reactions used to prepare polyether polyols. This catalyst is white or light yellow powder, is suitable for preparation of polyols with 1~6 functions. Compared with basic catalysts, this catalyst can be used with less amount (30ppm), and reaction time of polymerization is reduced largely, and the polyols products are not necessary to be refined. The DMC is suitable for using in common epoxide polymerization reactors, but it can be better if reactors have both of stirring and cycling systems.

When using the DMC, production period is short, thus the costs for production are reduced while the property of products are advanced.
